In order to meet the test requirements of missile-borne radar seeker batch production, a one-key test system for two-dimensional servo platform is designed. The test requirements of radar seeker 2D servo platform are analyzed, the test interface and test process of 2D servo platform are sorted out and unified, the general data processing method of automatic test process is established, and the man-machine interface of parameterized input and automatic output of statistical results is developed. By configuring the parameters, the one-key test of different types of radar seeker 2D servo platform products can be realized. The verification results show that the system can replace the manual operation test, and the efficiency is improved by more than 5 times, which can reduce the professional technical requirements and operation difficulty of testers, improves the reliability of product testing, and has high engineering reference value.
