摘要
在现有单脉冲测量雷达数字测速方法基础上,提出一种测速新方法。该方法通过加长积累时间,提高了测速的信噪比,并估计和补偿运动目标加速度等信息,获得更精确的频率,从而提高测速精度,同时完善频谱异常检测方式,使单脉冲测量雷达测速具有更好的稳健性。
A new velocity measuring method of monopulse instrumentation radar is presented based on the existing digital velocity measuring methods. The more accurate frequency can be acquired,and the velocity measuring precision can be im-proved by lengthening the integrating time,increasing the velocity measuring signal-to-noise ratio and estimating the moving ob-ject accelerated speed. The method improved the frequency spectrum exceptional detection mode and made the velocity detection of the monopulse instrumentation radar more robust.
