本文从模拟实验的角度,对脉冲多卜勒雷达信号自由分布秩处理进行了较详细的研究,并把求秩器与A/D变换器作了比较。证实了求秩器可以保留多卜勒信息;并得出在I、Q正交通道中分别发生限幅效应时,将可能在负的多卜勒频率上出现虚假目标谱线;同时,从保留信息和使输入量数字化的角度,提出了用求秩器代替A/D变换器,使设备进一步简化。
In this paper, from the perspective of simulation experiments, the pulse Doppler radar signal distribution of the rank of a more detailed study, and the rank of the device and the A / D converter were compared. It is confirmed that the ranker can preserve the Doppler information; and when the clipping effects occur respectively in the quadrature I and Q channels, the false target spectral line may appear on the negative Doppler frequency. At the same time, Information and digital input point of view, put forward the use of rank-class instead of A / D converter, the device to further simplify.
