摘　　要：讨论了一种基于低分辨雷达的目标(飞机)识别方法,描述了这种识别方法所依赖的硬件平台即目标回波数据采集系统的组成及工作原理,阐述了一种基于低分辨雷达的目标粗分类(目标大、中、小等粗略属性的判别)的方法,研究了低分辨条件下目标特征描述的思路, 尝试利用这些方法进行目标属性的粗分类以及进行机群目标架次的判别。现场实验表明,这 些方法是可行有效的,对于提高常规低分辨雷达的性能有着重要的意义。A method of automatic radar target recognition based on the low-resolution radar is discussed,and the hardware supporting the method is introduced,including the principle of the radar target data acquisition system.After the theory of target approximate identification based on the low-resolution radar is studied,the feature extraction-methods of the radar target are proposed,then these methods are used to classify a big,medium or small target and get the exact number of an air fleet.From the experiment we can draw a conclusion that these methods are effective.The result of target approximate classification and identification of the number of an air fleet using this target recognition method is considerably fine. The method is very significant to improve the capability of the low-resolution radar.
