We propose a method to extract the signals at a specific height from at least three SAR images with ambiguity suppression by using multiple baseline SAR interferometric phases. Our proposed method consists of two important steps. First step is the integration of complex numbers which consist of SAR image amplitudes and interferometric phases, and the second step is filtering based on interferometric phase with adjustment to the phase of specific height. As a result, the method extracts signals at a specific height from COSMO-SkyMed images with only three SAR images, and we further analyse the signals in height by theoretical considerations.
