Application of compressive sensing in 3D radar imaging

By using compressive sensing technique, the data rate needed in radar imaging can be remarkably reduced. Phase reservation is the key issue for compressive sensing based radar imaging algorithm. In this paper, we propose a phase-reservation CS based pulse compression algorithm after investigation of the radar signal sparsity property, and then apply the algorithm to 3D radar imaging. Simulation results show that the phase information after CS range compression could be well preserved so as to realize 2D and 3D radar imaging.
