摘要
针对复杂电磁环境中独立散射源参数的估算问题，提出了一种非相干变极化接收方案，有效地获取了反映散射源信息的４个参数．研究了非相干变极化技术对散射源参数的估算能力，针对具体应用背景，构建了几种典型的散射源参数估算模型，并利用一系列数值实测对这些模型进行了验证．
An efficient incoherent COP (Change of Polarization) receiving scheme was presented to extract 4 parameters, which contain the information of scatterers in view of estimation of scatterers parameters in the adverse electromagnetic circumstance. The estimation capacity of incoherent COP was investigated. Several characteristic parameter estimation models were constructed in connection with some special application backgrounds. Finally, conclusions and models were verified by a series of numerical examples.
