| 摘 要： | 探讨了利用雷达主天线变极化特性和辅助天线结合测量目标极化散射矩阵的可行性。首先给出了雷达主天线不同变极化方式下的接收信号模型和辅助天线的接收信号模型，其次根据主天线变极化方式的不同，提出了两种估计雷达目标极化散射矩阵的方法，并简要分析了其估计的精度。最后，结合暗室测量数据仿真分析了雷达目标极化散射矩阵估计的精度，验证了本估计算法的有效性。 |

| Abstract: | The feasibility of measurement of Polarization Scattering Matrix(PSM) of radar target using transmitting-antenna and sidelobe-canceller antenna is discussed in this paper.Firstly,received signal models of radar transmitting-antenna with sidelobe-canceller antenna are given.Then, two estimation algorithms of radar target's PSM,which are based on the differences of varied polarizations of transmitter-antenna are derived.Finally,the estimation accuracy and availability of radar target's PSM are analyzed through laboratory measured-data. |
| Keywords: | polarization scattering matrix measurement sidelobe-canceller antenna radar target |
