基于压缩感知的超分辨目标散射中心估计
Super-resolution Scattering Centers Estimation Based on Compressed Sensing
摘要
Abstract
Due to the requirement for feature extraction of scattering centers in radar target recognition , a method of super-resolution scattering center parameters estimation based on compressed sensing is proposed .By designing a dictionary, pulse compression signal is sparsely represented in this paper and then the CS framework is used to the reconstruction problem .Based on the simulation method, the correctness of our proposed scheme is verified .Through filtering a signal with 80 MHz bandwidth into a 20 MHz narrow-band signal, the super-resolution scattering centers are reconstructed by the 20 MHz signal and then wideband pulse compressed signal is recovered .Re-sults show that the proposed algorithm is feasible to reconstruct scattering centers with an acceptable error .关键词
