双通道两视干涉相位差解径向速度模糊方法
Solution to radial velocity ambiguity by dual-channel two-look interferometric phase difference
摘要
Abstract
Based on dual-channel two-look interferometric phase difference , a new method is proposed to estimate the radial velocity of a moving target unambiguously in the synthetic aperture radar/ground moving target indication ( SAR/GM TI) system . The two-look data is constructed in the range frequency domain , and interferometric phases of two-look are obtained by interferometry between the data of different channels . Since the interferometric phase difference of the two-look is not wrapped , the proposed method can be used to estimate the radial velocity of a moving target unambiguously . And the maximum unambiguous radial velocity is effectively improved by the proposed method . The effect on radial velocity estimation by the interval of the two-look data in range frequency is focused . Numerical and real data are processed to demonstrate the effectiveness of the proposed method .关键词
