In the radar imaging equipment test, the traditional real scene test method is difficult to construct, the scene is limi-ted, and the test risk is high, so it is urgent to solve the problems of insufficient testing and incomplete evaluation of the target recognition algorithm. Aiming at the existing problems, this paper designs a test system for the target recognition algorithm, which can provide the processing and labeling of SAR image and inverse SAR image, as well as the automatic operation, environment configuration and performance evaluation of target recognition algorithm. Compared with the traditional test method, the system has the advantages of low cost, short test time, strong controllability and extensibility.
