Extraction of Three-Dimensional Micro-motion Feature from Ballistic Target in Netted Radar
摘要
Abstract
Extraction method of three-dimensional micro-motion feature from sliding-type scattering center in ballistic target is studied.Firstly,the characteristics of sliding-type scattering center are analyzed in the paper,a new feature extraction method based on half period delay multiplication is introduced,and the mathematical relationships between sliding-type scattering center and ideal scattering center are built up. And then parameters are extracted from echo signals by utilizing the multi-view characteristics of netted radar.Through the structure of nonlinear multivariable equation systems,the three-dimensional micro-motion paracters and part of the structure features are solved by taking an extracted parameter as variate. The simulation results show that the proposed algorithm is effective.关键词
