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.
