摘要
研究了宽带相控阵雷达电扫描时的孔径渡越现象,分析了该现象的产生机理,指出了其对脉压成像的影响,提出了使用数字信号处理进行补偿的方法及其适用条件,并进行了仿真验证。最后就孔径渡越现象对宽带相控阵成像雷达脉压影响的补偿方法作了探讨。
The aperture fill phenomena arised from electrical scanning of wideband phased array radar is studied.Both the formation mechanism of the phenomena and the effects on pulse compression imaging are analyzed.A digital compensation method and its applicable condition are given,and the results are evaluated by simulation.Finally the compensation method of broadband phased array imaging radar pulse pressure effected by aperture crossover phenomenon is discussed.
