毫米波引信体目标模拟器的实现

Implementation of a MMW Fuze Body Target Simulator

介绍了一种脉冲多普勒毫米波引信体目标模拟器,它采用数字射频存储技术(DRFM)和数字直接合成技术(DDS),能模拟引信与真实目标在不同交会条件下的体目标回波信号,实现了体目标回波信号零延时,以及多普勒频率、幅度等重要参数的精确模拟。该模拟器可以用于毫米波引信的内、外场试验,测试引信对体目标交会时的启动特性,调整和优化引信的设计参数,从而大大提高引信的研制水平,降低研制成本。

This paper introduces a body target simulator of millimeter-wave Pulse Doppler fuze, which adopts the technique of digital radio frequency memory and digital direct synthesizing. This simulator can simulate the body target echo signal in different projectile-target encounter condition and many important parameters, such as zero delay, Doppler frequency and amplitude. It can be used to MMW fuze internal field test and field test, and also can promote the development level of fuze and reduce its cost by using this simulator.
