摘　　要：针对收发分时体制数字射频存储器(DRFM)干扰方式,提出一种能有效对抗此方式的多脉冲雷达信号发射样式。该方式在雷达接收机中分多路进行匹配滤波,利用干扰机收发分时体制,无论其转发接收到的任何一个脉冲,雷达方总能利用另一路正确检测目标。经理论分析与仿真表明,该方法简单有效。Aiming at the jamming mode of receiving/transmitting （R/T） time-sharing system digital radio frequency memory （DRFM）,this paper puts forward a multi-pulse radar signal transmitting mode that can effectively counter the jamming. This approach performs more than one matched fil- tering in radar receiver, and by using R/T time-sharing system of the jammer, the radar side always can use another to correctly detect the target whatever any received pulse is transmitted. Theoreti- cal analysis and simulation show that the approach is simple and effective.
