摘要：
InSAR terrain inversion has always been an important research topic, and phase unwrapping has been a key issue in InSAR. This paper proposes a new approach for InSAR that does not require phase unwrapping when the observed scene height is smaller than the ambiguity height, based on the analysis of InSAR ambiguity height. By combining the radar range Doppler equation, a three-dimensional point cloud reconstruction of the observation area is achieved. This provides a new perspective for InSAR-based Earth observation. Finally, the effectiveness of the method is confirmed through the processing of Ku-band measurement data.
