单脉冲技术通过比较单个脉冲多路回波信号的信息实现对目标角度位置的精确测量，广泛运用于跟踪雷达中。将其运用于成像中可以实现合成孔径雷达（SAR），多普勒波束锐化（DBS）等技术难以实现的前视成像，针对这一点，提出了一种单脉冲前视成像算法。实测数据处理结果表明，这种方法与实波束成像相比，可以显著改善图像质量，具有很高的实用价值。

Monopulse is a technique with which information concerning the angular location of a target is obtained by comparison of signals received in multi-channels.It is widely used in tracking radars.This paper proposes a valuable monopulse imaging algorithm for airborne radar forward-looking imaging.As is prored by experimental results, compared to the real-beam imaging method，this algorithm can provide remarkably improved images，which are difficult to be obtained by SAR or DBS.
