Target scattering centers reconstruction based on C-means method for radar network

Conventional synthetic aperture radar (SAR) and inverse SAR (ISAR) techniques need long integration time, i.e. 1 second or more, to get the high azimuth resolution. Radar network with widely separated transmitters and receivers has the ability to simultaneously acquire the high range resolution profiles (HRRPs) from different angles and thus has the potential to reconstruct the target image by combining the information from these HRRPs. This paper proposed a target reconstruction algorithm based on the C-means method for radar network. The reconstruction could be accomplished by using fuzzy clustering of C-means method based on these HRRPs. The simulation results validated the proposed algorithm.
