摘要
分析了孔径渡越时间对相控阵雷达信号的影响,它包括信号的时移、幅度加权和能量损失。提出一种基于信号处理方法的相控阵雷达孔径渡越时间数字补偿方法,可以补偿孔径渡越时间引起的信号时移和幅度加权。通过对典型阵列孔径渡越时间的补偿仿真,表明该方法的正确性和有效性。
This paper analyzes the influence of aperture fill time on phased array radar signal, which includes signal time shift, amplitude weighting and energy loss, presents a digital compensation method o{ aperture fill time for phased array radar based on signal processing method, which can compensate the signal time shift and amplitude weighting caused by aperture fill time. Compensation simulation of aperture fill time for typical array shows the correctness and effectiveness of the proposed method.
