距离扩展目标检测的研究

Detection of Range Spread Target

本文以脉冲串作为距离扩展目标的回波模型，根据回波信号的不确定性，分别以相干脉冲串、非相干脉冲串及振幅独立起伏的非相干脉冲串的检测来讨论高距离分辨雷达的检测问题，并实测了Ｎ１７飞机缩比模型的回波信号，给出了相应检测性能改善的估计。

In this article,the backscatter signal of range spread target is modeled as a train of pulse. The detection of high range resolution radar is dealed as the detection of coherent pulse train,incoherent pulse train and fluctuating incoherent pulse train respectively according to the uncertainty of the backscatter signal. The improvement of the detection performance of high range resolution ra-dar is evaluted on the basis of measurement of F 117 scale model.
