1. A method for generating a 3D image of an area, wherein the 3D image is a synthetic aperture radar (SAR) image, comprising the steps of:
- acquiring multiple data sets from the area using one or more SAR systems, wherein each SAR system has at least a pair of parallel baselines and multiple pulse repetition frequency (PRF), wherein a predetermined PRF for each baseline is randomly selected from the multiple PRF to be different from other PRF;
registering and aligning the data sets to produce aligned data sets; and
applying a 3D compressive sensing reconstruction procedure to the aligned data sets to generate the 3D image corresponding to the area, wherein the steps are performed in a processor.

Abstract
A method generates a 3D synthetic aperture radar (SAR) image of an area by first acquiring multiple data sets from the area using one or more SAR systems, wherein each SAR system has one or more parallel baselines and multiple pulse repetition frequency (PRF), wherein the PRF for each baseline is different. The data sets are registered and aligned to produce aligned data sets. Then, a 3D compressive sensing reconstruction procedure is applied to the aligned data sets to generate the 3D image corresponding to the area.
