摘要
分析了重频捷变电路对雷达导引头在杂波环境下目标检测性能的影响,提出了一种在时域设计滤波器引入杂波相关特性并动态更新滤波器的仿真方法。仿真结果表明:在重频捷变模式下,杂波幅度分布概率密度曲线变得尖锐,杂波相关性减弱。得出的结论:重频捷变可以提高导引头的目标检测性能。
The influence of PRF agile circuit on radar seeker target detection performance under the clutter environment was analyzed, and a kind of simulation method by introducing clutter correlation property in filter design and dynamically renewing the filter at the time domain was proposed. Simulation results showed that the clutter amplitude distribution probability density curve becomes sharp under the PRF agile model, and clutter correlative property weakens. So PRF agile can improve the target detection performance of radar seeker.
