Abstract:

Radar seeker is the basic component of precision guided air-to-air missile, to achieve the functions of missile detection, guidance and control.The seeker with complex function and structure needs to go through many tests, in order to ensure the pass rate in the production process.That made a large amount of test work. In order to improve the efficiency of the production test, the automatic test system of the radar seeker is designed and realized, and the software and hardware design is completed.The circuits for accqusition, communication, control and protection will be introduced in the hardware part.In order to realize the programming and fault debugging of the program,the DSP debugging system was Designed.The software part completed the design of each functional module according to the work flow and index requirements of the seeker, and the automatic testing system.The software based on LabWindows / CVI development has simple interface and convenient operation.The system can record all the test data and process data, improve the traceability of the production process. The practical application shows that the system has good performance, high reliability, long-term and stable operation and meets the design requirements.
