Airborne Anti-radiation Missile Weapon System Of Passive Detection And Location Principle And Flight Experiments

With the rapid development of science and technology changes with each passing day, the development of modern war more and present a diversified and multidimensional characteristics. The intelligence reconnaissance in multi-dimensional space has become the primary task of the war, and the first priority of intelligence reconnaissance is to pinpoint on enemy targets. At present, with the rapid development of "soft killing" technologies such as electronic countermeasure and electronic jamming, and also with the development of battlefield "hard kill" weapons such as anti-radiation missile, the traditional radar positioning technology is faced with great threat. In the trend of increasing emphasis on stealth attacks and hard kill, passive detection positioning technology which has the advantages of much higher range, strong emergentness and hidden, not easily spotted and disturbed by the enemy, has become a focus on the development of the military powers. Passive detection technology play an important role on electronic warfare aircraft, anti-radiation missile weapon system, airborne radar warning system, and has an important effect in improve the attacking side under the complex electromagnetic environment of operational capability, reduce the battle damage. So this article introduces the principle of airborne passive detection and location technology, and present the flight test.This thesis firstly studies the technology of passive detection to the radiation target in a certain type of aircraft airborne anti-radiation missile weapon system, and then analyses the aircraft airborne anti-radiation missile weapon system of launch conditions of aircraft target passive localization algorithm accuracy, also adopt the combination of theoretical analysis and actual flight test method, designed the detailed air flight test method. In view of the flight test, the article through analysis the specific content of flight test needs assessment and method, data collect and record the testing method is studied. According to the requirements of the test, studying the "passive detection alarm 360° azimuth accuracy test flight routes". Through the actual test for the airborne electronic warfare system of passive detection accuracy of azimuth data, infer the "passive position precision flight routes", and developed a set of how to minimize the input data error effect on passive positioning precision of model test method. At the same time use the air "localization success and give up" operation method, the greatest degree of reducing the test flight vehicles, save a lot of money. Finally, the application of research results of this paper, the equipment of a certain aircraft airborne anti-radiation missile passive detection related features of passive location system, tactics and remember to evaluate the actual air flight test performance indicators.In the end, this paper for the passive detection positioning of the function, principle, and performance of airborne anti-radiation missile weapon system to flight verified, evaluate the positioning accuracy, and obtain some valuable test results. The test results and the method summarized provide rich engineering experience in our country’s special electronic warfare, the airborne electronic warfare equipment, as well as new type airborne anti-radiation missile weapon system flight test, how to improve the technical level of our military weapons and equipment and provide some reference for this field in the future.
