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。
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.
