摘要
定量分析了阵列孔径、干扰信号带宽、通道幅相误差以及Ａ／Ｄ变换器的量化噪声对大型稀布圆形阵列天线干扰对消效果的影响，介绍了稀布阵综合脉冲孔径雷达（ＳＩＡＲ）采用抽头延迟线以提高干扰对消性能的方法，并给出了数值计算与计算机模拟结果。
The effect of the aperture of array, bandwidth of interference, qualitization noise of A/D converters and errors of amplitude and phase in channels on the performance of interference cancellation in large sparse circular arrays is analyzed. The tapped delay-line processing improves the performance for Synthetic Impulse and Aperture Radar (SIAR). Computer simulation and some numberical results are also provided.
