针对某准连续波侦察雷达的特点，提出了在零中频上实现主杂波对消的方案，研制了数字式零中频杂波对消器。该对消器采用三脉冲对消方案，脉冲重复频率可编程。实测的对消器特性曲线与理论设计曲线相吻合。

A method of digital clutter cancellation used in a certain quasi-CW radar is presented in this paper, and a digital clutter cancellation circuit is designed. Three pulse cancellation method is used and the PRF is programmable. Experiments show that measured results coincide with the theoretic analysis.
