| 摘 要： | 在自卫噪声干扰下,单脉冲雷达可以从有源跟踪方式转为无源跟踪方式,利用敌方释放的噪声干扰进行无源跟踪.首先对有源角跟踪精度进行了分析与计算,然后在无源跟踪时两路接收支路不对称、噪声干扰振幅起伏、中放带宽有限和归一化受到破坏等主要误差原因分析的基础上.对无源角跟踪精度进行了估算.得出一般情况下无源角跟踪误差大于有源角跟踪误差的结论.

| Abstract: | Under self-defense noise jamming,monopulse radar can transfer work way from active tracking to passive tracking and use noise jamming released by the enemy to track passively.Angular tracking precision of active tracking is firstly analyzed and calculated,then angular tracking precision of passive tracking is estimated based on main error cause analysis in passive tracking,such as the dissymmetry of two receiver branches,amplitude fluctuation of noise jamming,the limited bandwidth of IF amplifiers and norma... |
