基于多视角距离像的弹道目标三维微动特征提取
Three-Dimensional Micro-motion Feature Extraction of Ballistic Target Based on the Multi-view Range Profile
摘要
Abstract
To solve the problem of single scattering point type of feature extraction of existing estimation method,and the difficulties of engineering implementation,a kind of method for extracting three-dimen-sional precession features based on netted radars is proposed.Firstly,the length of the radar line of sight direction between two strongest scattering points is obtained by using the netted radar to observe range profile sequences of ballistic target,and the relation that proj ected lengths with time is extracted.Then, the parameters in the equation is estimated by the Least squares estimated method (LSCE).After that, profited from the multi-view of netted radar,Three-Dimensional Precession Features is extracted on the basis of proj ected components of different precession angular frequency.Computer simulation proves the effectiveness and stability of the extraction method,and the results reach up to the expected effects.关键词
