| 摘 要： | 为得到弹目交会过程中超宽带无线电引信接收机的时域输出信号,实现高速交会条件下引信接收机的性能优化,推导了取样积分微分电路的时域数学模型,提出了一种基于无载波信号时域多普勒效应的接收机输出信号时域仿真方法.弹目接近速度对接收机输出信号的影响研究表明,输出信号频率与弹目接近速度成正比;信号幅度与弹目接近速度关系曲线存在速度驻点.选择合理的积分、微分电容可设置恰当的速度驻点,提高引信的抗干扰性能.

| Abstract: | A time domain mathematical model of sampling integral differential circuit is designed in this paper in order to obtain the output signal of ultra wideband(UWB) radar fuze receiver during missile target encounter and optimize the performance of receiver.Considering the time domain Doppler effect of carrier-free signal,a time domain simulation method for the receiver output signal is proposed.The receiver output signals with different missile-target closing velocities have been simulated.The simulation resul... |
