Abstract： Pulse radar is the backbone measurement and control equipment in our country. Because of its narrow beam, it is always difficult to capture and track in the measurement and control task. For many years, measurement and control technicians have been studying and exploring the simulation actual combat training in different ways. The traditional RF simulator is realized by the up-conversion mode, which has huge equipment and high price. This paper introduces the basic composition of measurement and control equipment and the formation process of sum and difference signal in pulse radar. Based on the practical radar system, the software module is used to realize the control hardware of the upper computer system and the information transmission with the radar equipment. C-band radar analog signal is generated by AD9361 RF chip. Through the test and verification on the radar equipment, the software radio technology is successfully realized to generate the C-band RF signal, which solves the problem of insufficient actual combat training means for equipment personnel, further improve equipment personnel tracking capture and emergency disposal ability, is an important means to test the technical and tactical performance of the equipment.
