In this paper, a ground-based experimental system of SAR tomography is proposed in detail. Based on the analysis for the properties of signal in the height direction of SAR tomography 3-D imaging system, the effect and relationship of parameters related to resolution in the height direction are discussed, and proper experimental system parameters are proposed. By using the general SAR tomography imaging...
In this paper, a new airborne radar system for three dimensional SAR tomography is proposed. The multiple antennas are amounted under the wing of airplane with one transmitter element and all receivers. The signal model of this system is presented and the unambiguous elevation is given. The feasibility is validated by simulation results both from single flight and multiple sparse flights.
In this letter, a novel approach for the coregistration of synthetic aperture radar (SAR) images is proposed based on the level set method. The features of regions are detected by segmenting the images, and the images are coregistered by matching the detected features. The energy functional of level sets is formulated with respect to detecting and matching features. The coregistration is achieved...
