| 摘 要： | 极化测量技术是现代雷达领域的重要发展趋势之一,对目标极化特性的测量是实现极化雷达的关键技术,但在工程实现上存在很大的技术挑战.针对这种情况,提出了一种新体制目标特性测量雷达的理论模型,即正交极化二元阵.初步证明了该式天线具有明显的极化空变特性,进而设计了一种新的极化测量处理算法,仅需一个接收处理通道即可在天线波束扫掠目标时,实现目标极化散射矩阵的测量.通过紧凑场微波暗室对自行搭建的正交极化二元阵进行了全极化宽带动态测量实验,利用实测数据处理验证了上述研究的正确性.研究结果对于挖掘现有雷达装备的极化测量潜力,提升其信息获取与处理能力,具有一定的启发意义.

| Abstract: | Polarimetry is an important trend in the development of modern radar.The technique for measuring polarization scattering property of the target is the key for polarization radar realization,but it faces challenges in engineering.Here,a new theoretical model for target scattering characteristic measurement radar,named orthogonal polarization binary array radar (OPBAR),is proposed.The spatial polarization characteristics of the radar antennas are addressed.A new polarimetric algorithm that needs only one chan... |
