Abstract： The interface recognition of inside computer is used in automatic test of radar countermeasure ce system. It can get high recognition rate using BP neural networks. First, the theory of BP neural networks is introduced, and then the paper gives the de- sign method as a whole, and designs the server and the client. After that, the realization of recognition module is given. At last, the system is improved based on the trait of interface of inside computer, which improved the recognition rate. The entire system is efficient in speed, recognition and precision, the number recognition rate can reach 98 percent, and the letter recognition rate can reach 96.5 percent. It has high prospect.
