Abstract本文分析了信道互耦和不平衡度对干涉式综合孔径微波辐射计复相关干涉测量的影响.分析表明干涉测量误差的主要来源是信道的相位不平衡度.实现信道中心频率的相位精度就可以保证干涉相位的精度,而信道内的残余相位差只会引起干涉相关度的降低,通过相干/不相干噪声校准,就可以对信道不平衡引起的干涉相关测量误差进行修正.
Other AbstractIn this paper ,the effects from mutual coupling and imbalance between channels on the interferometric correlation are analyzed. It is shown that the correlation error is mainly introduced by the phase imbalance. The phase balance of the central frequency can ensure the accuracy of the correlation phase ,and the residual phase error will only reduce the coherency. Coherent/Incoherent noise calibration can correct the channel imbalance related interferometric correlation errors.
