本文简要介绍了两种采用电荷耦合器件(CCD)的动目标显示对消器。一种为四路并行钟脉冲交错采样系统
它适用于脉冲宽度较窄的雷达;另一种为单路一次对消器
它适用于宽脉冲雷达。
This paper describes the development of two types of CCD MTI cancellers. One is a four channel parallel-operation system with sampling frequency of 2.1 MHz. In this system the .clocks between adjacent CCDs are alternated in lower frequency overlapping mode. The system is very suitable for narrow pulse radars. Tke other is a single channel two pulse canceller with sampling rate of 250kHz.This system can successfully be applied to wide pulse radars.
