Visual measurement method for seeker performance of guided weapon system

Presently, indoor simulation and live ammunition firing are the main methods to evaluate the guidance performance of guided weapon system. However, due to the limitation of simulation conditions, there are some problems in indoor simulation such as inadequate description of target transient mechanism and low reliability of process reproduction. For live ammunition firing, the limited sample size, single environment settings and inconsistency of firing conditions limit the application. And this make it difficult to comprehensively assess the environment adaptability of weapon system. In order to solve this problem, an intermediate verification and assessment method was proposed for the real complex battlefield environment. In this work, a visual dynamic test platform for the guidance weapon system was constructed to obtain synchronization and real-time visualization of the seeker detection, recognition and tracking targets. The target information was extracted and the guidance performance was evaluated. Using this method, static and dynamic tracking tests could be carried out for actual target in shooting range environment. It can conduct integrated tests for seeker systems with different guidance modes such as laser, millimetre wave, television and infrared. It can provide direct data of targets and backgrounds for indoor simulation to improve simulation fidelity. It can also repeatedly check the key ability of guidance link and make up the insufficiency of firing test quantity of live ammunition. This would provide a new test and verification for weapon system development.
