Abstract:

Seeker is the core component of the airborne missile. It achieves detection, guidance and control functions. Its performance will directly affect the missile tracking and intercept accuracy.In order to test the Radar Seeker completely, the Radar Seeker test system based on CPCIbus is designed in this paper. The subjectintroduces the design ofthe IPC, hardware board, conditioning circuit and peripheral, especially the reliability of the circuit. The software system coordinated control products, angular position simulator, echo simulator and rotary table. Then the system finished the test function of each module and product testing through the flow of data transmission.The system can simulate the workplace of radar seeker,set the parameters of the seeker and receive information transmitted by the seeker.And then the precision,sensitivity,reliability of seeker can be tested by the system.The experiment and application show that this test system has good performance, high reliability,and achieve the design requirement. 
