摘要
基于宽带相控阵雷达孔径渡越时间对一维距离像影响的分析,提出了一种孔径渡越时间数字补偿的方法。根据线性调频(LFM)信号的解线性调频处理特点,采用时间补偿处理。在子天线阵实现实时延迟补偿。实验与仿真结果表明:该法可对孔径渡越时间进行有效补偿,具一定的参考价值。
A compensation method of asperture fill time was put forward based on the analysis of the effect of phased array radar s range profile caused by aperture fill time in this paper.According to the characteristic of linear frequency modulated signal,the compensation of time delay in real time was realized in sub array using time delay unit.The results of experiment and simulation showed that this method was effective.
