"Jianxiang" anti radiation UAV can really suppress s
figure note: "Jianxiang" UAV and its launch vehicle
in August 2019, Taipei International Aerospace and national defense industry exhibition was held. At this exhibition, the new anti radiation UAV "Jianxiang" and its box launch vehicle developed by "Zhongshan Academy of Sciences" made its public debut for the first time, and attracted extensive attention from Taiwan media. Taiwan media all boast that the anti radiation UAV "can effectively counter the S-400 new air defense missiles deployed by the people's Liberation Army along the coast of the mainland". Then, is the "Jianxiang" anti radiation UAV called "Taiwan habi" really so powerful
Taiwan began to pay attention to anti radiation warfare very early, and actively sought to obtain anti radiation missiles when introducing "phantom" and F-16 fighter planes. Although Jixi has selected the future successor industry under Taiwan's repeated requests, the United States has sold a small number of agm-88b anti radiation missiles to it, but this is an old model that has been discontinued since 1993, and its performance and reliability are not very reliable
the number of agm-88b sold by the U.S. military to the Taiwan air force is too small, which is regarded as a "trump card" weapon that cannot be lightly used by the Taiwan army. However, the radar and air defense networks of the mainland on the right bank of the Taiwan Strait are becoming more and more dense, especially after the S-400 purchased from Russia has been in service, with its range of hundreds of kilometers, as long as it is arranged along the coast of Fujian, it can effectively control and cover Taiwan's airspace, and cooperate with the air force fighter + tactical missile, The Taiwan air force can be closely monitored and continuously attacked by our army in the three stages of take-off, take-off and stagnation. It is difficult for Taiwan Air Force fighters to survive such high-intensity surveillance and attack. To break this desperate situation, we must first "tear open" the dense radar network of the mainland, and in addition to anti radiation missiles, there is also the sharp weapon of anti radiation UAV
figure note: agm-88e is the best anti radiation weapon in Taiwan's heart. Why the United States doesn't sell it?
after Israel delivered a batch of "habi" anti radiation drones to China in 2000, Taiwan's military on the one hand deeply studied how to fight against "habi" anti radiation drones, On the other hand, it actively seeks to introduce the "habi" anti Henan League group from Israel, and the annual output of 600000 tons of aluminum deep processing high-end aluminum project has officially started the construction of radiation UAV or its related technology. Although Israel categorically rejected Taiwan's military, since the design concept and some technical data of "habi" anti radiation UAV are public, Taiwan's "Chinese Academy of Sciences" began to develop anti radiation UAV with reference to "habi" since 2002
it is reported that the anti radiation UAV project carried out by Taiwan's "Chinese Academy of Sciences" is code named "Jianxiang plan". Because its shape is similar to the "harpy" UAV developed by Israel, it is called "Taiwan's version of harpy"
Taiwan's self-developed "Jianxiang" anti radiation UAV has obvious advantages. First, it can produce and equip a large number of anti radiation UAVs without being restricted by the United States on the number of anti radiation missiles, and impact and destroy the air defense, reconnaissance and surveillance radar network of the mainland in the mode of "UAV group"; Secondly, low altitude and low-speed anti radiation UAV and high altitude and high-speed anti radiation missile can form a good "high-low combination", playing a role of 1+1>; 2 to enhance Taiwan's anti radar combat capability, so as to suppress mainland air defense missiles in the Taiwan Strait and cover the use of Air Force fighters
performance analysis: the early "habi" imitation
1, launch vehicle
from the appearance, the "Jianxiang" anti radiation UAV system adopts the design idea of a mobile launch system that is consistent with Israel's "habi" and China's domestic anti radiation UAV system, but its launch vehicle is not the high mobility 6 adopted by China and Israel × 6 military trucks, but 4 × 4. The truck trailer mode of heavy-duty truck head + 4-wheel trailer has the advantages of large load and capacity. It carries a total of 12 integrated launch box systems, and adopts the arrangement mode of three launch boxes in four layers, with the launch box slightly inclined upward. The mobile launch systems of Israel and China have only two layers and six launch boxes, which makes "Jianxiang" have the advantages of large number of one-time launches and strong saturation attack capability. However, the weakness of the launch vehicle is also obvious, that is, the length of the trailer is too long, and the system integration is not high enough. Part of the chassis has to be arranged on the chassis between the wheels, which further compresses the ground clearance of the chassis, further reduces the trafficability of the vehicle, and the mobility is similar to 6 × 6 motor vehicles cannot be compared at all, which reduces the battlefield viability of the "Jianxiang" anti radiation UAV system

2, the UAV platform
"Jianxiang" anti radiation UAV, like "habi", adopts a small aspect ratio delta wing non flat tail layout, the fuselage is cylindrical, integrated with the wing, and the head of the cylindrical fuselage is equipped with a passive radar seeker, The seeker technology comes from Taiwan "Tianjian" -2a anti radiation guide Jinan new era Gold Testing Instrument Co., Ltd. the plastic coated metal hose tensile testing machine introduced here is mainly aimed at the seeker technology of the tensile test bomb of the plastic coated hose of wires or cables in the electrical system of machine tools. It is worth noting that we can see that the sweepback angle of the wing of the "Jianxiang" UAV looks larger than that of the "habi", which means that the slenderness ratio of the "Jianxiang" UAV is slightly larger than that of the "habi". Therefore, it can be speculated that the maximum speed of its dive attack is more than 400 km/h, the actual ceiling can reach 3000 meters, and the actual combat radius available in actual combat will not be less than 400~500 kilometers
3. The guidance technology is backward.
the radome of the seeker of the "Jianxiang" UAV is not transparent. It can be seen that it does not use optical sensors, but only uses passive radar seeker. This technology is in the same vein with the early type of "habi". However, in fact, on the "habi" enhanced and asn-301 anti radiation UAV developed in Chinese Mainland, the seeker technology has been greatly updated and evolved. In addition to installing the anti radiation receiver system, two guidance modes of photoelectric video reconnaissance and real-time image transmission have also been added. In this way, in addition to receiving radar emitter signals, Asn-301 UAV can also use the photoelectric video guidance system of the head to firmly lock the target of the enemy radar station. At this time, conventional electronic countermeasures such as decoy radiation source jamming or radar shutdown are completely ineffective for the new anti radiation UAV, which greatly enhances its anti electronic interference ability and hit rate. At the same time, the real-time image transmission system can send the photoelectric reconnaissance video back to the headquarters in real time through the data link, and the headquarters can control and command it remotely, which is also conducive to improving the reasonable allocation and Strike ability of targets. It can be seen that the guidance system of "Jianxiang" is single, which is a major defect in actual combat. On the one hand, the passive receiving seeker is easy to be disturbed by the decoy radiation source, and the anti-jamming ability is very poor; On the other hand, radar shutdown confrontation is a common means to combat anti radiation UAVs and anti radiation missiles. Only installing passive seeker can easily cause the guidance system to "blind" and fail to hit the target under the enemy radar shutdown means

"Jianxiang" UAV, which is embarrassing and widely used.
Guo Chengbin, general manager of Shenzhen Zhiwu contact Co., Ltd., has made outstanding achievements in the direction of integrated communication and industrial IOT. Although Taiwan boasts that the "Jianxiang" anti radiation UAV can suppress the S-400 long-range air defense missile system, in fact, people with a clear eye know at a glance, Compared with the new generation of anti radiation UAVs represented by Israel's "Halop" ("habi" enhanced) and China's asn-301, the so-called "big killer" of this fake Israeli "habi" UAV in the early 1990s has fallen behind for about 20 years in terms of overall technology and comprehensive performance. It can be said that it has fallen behind at birth and is embarrassing to use. As early as the beginning of this century, Chinese Mainland has purchased, used and imitated the "habi" anti radiation UAV, and has developed several generations of anti radiation UAVs based on it. Not only is it much more advanced in technology than the "Jianxiang" anti radiation UAV, which is only equivalent to the early type of "habi", but also in the use and research of anti radiation UAVs for many years, With mature methods to use and combat anti radiation UAVs, anti radiation UAVs are not new to us at all, and there are no secrets to speak of. We have targeted ways to deal with its weaknesses. On the other hand, from the level of "Jianxiang" UAV, it can be seen that Taiwan's anti radiation UAV not only has backward performance, but also their understanding of anti radiation UAV is obviously not deep enough. This makes us have an absolute advantage in the use and confrontation of anti radiation UAVs
