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.
