摘要
重点研究了脉冲重复频率对火控雷达STAP性能的影响,不同脉冲重复频率会造成杂波谱的分布发生改变,中(低)脉冲重复频率下,地杂波谱存在不同程度的模糊。仿真结果表明高脉冲重复频率下STAP性能优于中(低)脉冲重复频率,实飞数据也验证了本文的结论。
The influence of pulse repeat frequency on the STAP of a certain type of fire control radar was studied. Different pulse repeat frequency will lead to the change of clutter spectrum distribution. Clutter spectrum in joint space-time domain will be obscured because of medium or lowpulse repeat frequency.Simulation results probed that the STAP under high pulse repeat frequency has a high performance compared with that under medium or lowpulse repeat frequency. The measured data also testified this conclusion.
