A HYBRID SIMULATION SYSTEM FOR THE ANTUAMMING CHARACTERISTICS OF RADIO PROXIMITY FUZES

Presented in this paper is a hybrid simulation system for the antijamming characteristics of radio proximity fuzes. The architecture of the system and key techniques such as the mathematical models of the main parts and the system software design are discussed in detail. The system can be used in the field test simulation of radio proximity fuzes for projectiles, rockets, bombs, and mortar shells. The system includs both physical and mathematical models. The jammer and fuzes under test are physical models, while the antenna patterns of the jammer and fuzes, the trajectory, the space geometric disposal of ECCM field tests are in their mathematical models. To simulate the process of reconnaissance and frequency guidance, a subsystem is made up of a searching receiver and the jammer, microcomputer and the special interfaces. Using the system, the process of field test and the data concerned such as the space coordinate of burst can be displayed, copied and stored.
