Abstract: Aim at the searching and identifying low-speed targets of microwave telemetry radar, by the way of theory analyse and computer simulation to expound the theory and design of the microwave telemetry radar system. Base on the main functions of the microwave telemetry radar system and the technology characteristics of monopulse radar, the text analyses the theory of the microwave telemetry radar system and does simulations by computer, and then sets up the modularize functions,finally by the way of joint simulation of the whole microwave telemetry radar system to achieve the basic function in simulation of the microwave telemetry radar system. The microwave telemetry radar system will provide a theory flat roof for the engineering applications of telemetry radar, prove that the microwave telemetry radar system can do the inspect of ground.
