| 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 ar... |
