Based on compressed sensing, an inverse synthetic aperture radar (ISAR) enhancement technology is proposed. The ISAR enhanced imaging system is constructed, and then utilising the sparsity of multi-radar signals, the optimum function for point enhancement and edge enhancement is established. Compared with spectral estimation methods, the new processing provides a higher quality ISAR image without the number estimation of scattering centres. Simulation results demonstrate the validity of the proposed processing.
