鸟群类自然干扰目标的雷达探测与识别

Radar Detection and Identification of the Natural Jamming Target From the Birds

鸟群目标形成的干扰通常被划分为自然界杂波干扰的一种,但鸟群回波与通常的杂波干扰如地杂波、海杂波以及气象杂波不同,鸟群目标具有一定的速度、高度,容易形成一定的航迹,传统的MTI以及MTD雷达通常无法滤除鸟群目标。本文研究了鸟群的雷达目标特性以及雷达探测识别技术,对鸟群目标的RCS特性、雷达回波特征以及雷达探测特点进行了仿真分析,仿真结果可以为鸟群目标的雷达探测与识别提供帮助。

The jamming formed by the target of birds is usually classified as a kind of clutter jamming. But the echo of birds target is different from the normal clutter such as the earth clutter, the sea clutter and the meteorology clutter. The birds target has a certain speed and height and is easy to form a certain track. Traditional MTI and MTD radars usually can’t filter out targets of the birds. In this paper, the characteristics of the birds for radar are studied. The technology of the radar identification and detection, the RCS characteristics of birds, the characteristics of radar echo and the features of radar detection are also simulated and analyzed. The simulation results can be helpful for radar detection and identification of the birds.
