摘要
针对圆锥扫描体制雷达对目标精密跟踪及测角时由于导弹目标自旋而引起的跟踪失控问题,提出了一种采用窄带FIR滤波器滤除自旋调制信号,提取锥扫信号的解决方法。FIR滤波器具有线性相位,但需要采用高阶滤波才能达到很好的带通特性。该方法经过计算机仿真产生高阶FIR滤波器系数,经过了仿真验证,并在导弹目标跟踪应用中取得了很好的效果。
In this paper, the theory of conical scan radar is introduced, and a method is proposed to solve the problem brought by missile spinning during precision tracking and angle measurement. A narrow- band FIR filter is used to remove the modulated spinning signal and extract the conical scanning signal. This method has been successfully used in a radar.
