摘要 给出了一种综合孔径微波辐射计二维圆周非均匀分布阵列的排布方案,并在此基础上分析了信道串扰、信道不平衡、系统噪声等产生的误差,建立了各种误差的特性仿真模型。然后给出了各误差的补偿方法及噪声的消除方法,通过BG反演算法实现了在各种误差下的亮温反演,证明了以上误差补偿的有效性。 This paper presents analysis of errors in channels such as mutual-coupling,channel imbalance,system noise for a circle-array synthetic aperture microwave radiometer arrangement,and the simulation models are established.The error compensation method,noise elimination and image retrieval based on BG algorithm are given.Simulations show the compensation method of channel errors is valid.
