The signal characteristics of the FSK radar seeker and the basic methods of simulating the RF environment of the FSK radar are introduced. The project implementation and key technologies of instantaneous frequency measurement simulation and RF delay line simulation are emphatically discussed. It is pointed out that improving the frequency calibration method is the key technology to improve the accuracy of frequency guidance in the simulation of instantaneous frequency measurement. The development of low loss, wide frequency band and continuous delay time Adjustable high-performance RF delay line is the key technology of RF delay line simulation program. The characteristics of the two simulation programs are compared.
