Study on ATR Technology of Ground-Based Radar Station for Active Radar Seeker

摘要

摘要: 该文针对主动雷达导引头对地面防空单元制导雷达站的识别问题，在天线电磁散射特性研究的基础上，提出了雷达天线的多特征融合识别算法。首先对相控阵雷达天线的电磁散射特性进行了建模和计算，然后采用多普勒波束锐化技术对目标进行2维成像以提高天线的检测概率并估计目标雷达天线的RCS序列，基于RCS序列的幅度特性与周期特性，构造了相控阵天线的4类特征，并提出了相应的识别算法及融合识别算法。仿真实验表明算法具有较高的识别概率。

Abstract: In order to solve the problem of recognition to the ground-based radar station using an active radar seeker, the fusion recognition algorithms are put forward. Firstly the electromagnetic scattering model of the phased-array antenna is established. Then using Doppler Beam Sharpening (DBS) technology to improve the detection probability and to estimate targets RCS, then based on the extracted features－the range property and the period property of RCS, four kinds of characteristics of phased-array radar antenna are constituted. Finally the recognition algorithms as well as the fusion technique for target recognition are put forward. The simulation experiment indicated the effectiveness of the algorithm.
