基于压缩感知的SAR海面场景目标数据压缩与重构方法
SAR data compressing and reconstructing method for sea scene target based on compressed sensing
摘要
Abstract
The compressed sensing theory(a new data compressing and reconstructing theory)is utilized in this paper to solve the issue of huge SAR data compressing and reconstructing for sea scene target. Firstly,random Gaussian noise matrix is designed as a measurement matrix to complete data compressing. Secondly,smooth L0(SL0)algorithm is utilized to reconstruct original signal. On the basis of that,traditional frequency scaling(FS)algorithm is carried out to obtain the final SAR image. The effectiveness of the proposed method can be proved by simulation results.关键词
