研究圆锥扫描体制雷达中由于目标自旋引起干扰的问题,通过应用低通FIR滤波器,从包络信息中提取出了目标的旋转信息;用高通FIR滤波器,从包络信息中提取出了带有角误差信息的信号,经过处理降低了跟踪误差.
The paper deals with the problem of interference caused by the spinning of the target in the conical scanning system radar. It abstracts the revolving information of the target from envelope information by using the low-pass FIR filter; and abstracts the signal with angle error information from the envelope information by using the high-pass FIR filter, which are processed so as to reduce the tracking error.
