Radio amendatory channel is used in command guidance for missile, whose working state has direct influence on the precision of a missile. Therefore, it’s necessary to design a radio frequency detector for cycle detection of radio amendatory channel. After analyzing operating principle of the radio amendatory channel, the paper proposes a detecting program, introduces hardware and software design of radio frequency detector including high frequency receiving module, intermediate frequency receiving module and information processing module. The radio frequency detector has been applied in detecting airborne radio amendatory channel successfully improving support efficiency, and provides a reference for detecting other radio frequency.

Before final assembly and while debugging a missile, in order to ensure the flight control system can work stably and reliably, it is necessary to develop an auto test system. Test software is an important part of the test system. After describing the composition and working principle of the flight control system, summarizing the test requirements, the test software is designed. The design ideas, test algorithm, realization and key technologies, software anti-jamming techniques are introduced in detail. The test software guarantees the test system test the flight control system generally and reliably.

Before final assembly and while debugging a missile, in order to ensure the flight control system can work stably and reliably, it is necessary to develop an auto test system for a general performance test, including electrical performance, inertial measurement device and navigation accuracy. After describing the composition and working principle of the flight control system, summarizing the test requirements, this paper puts forward to a test plan based on a industrial computer, introduces the hardware design and hardware anti-jamming techniques in detail. The test system with self-test function has been applied in testing the flight control system generally and reliably.
