摘要
In order to overcome the problems encountered by traditional radar target extracting method, a radar target extracting method based on the decompositions of assemblies is proposed for high-resolution radar images. Since the attributed scattering center model is capable to represent the electro-magnetic behaviors of manmade assemblies, it is advisable to decompose the radar signal into assemblies. Then, by setting a constant-false-alarm-rate threshold to the energy of decomposed assemblies, assemblies belonging to the target are determined. Experimental results validate the superiority of the proposal over the traditional method under low signal-to-noise ratio environment with same constant-false-alarm-rate probabilities. Moreover, the integrities of assemblies is enhanced. Copyright © 2015 by Editorial Department of Chinese Journal of Radio Science
