Attitude inversion of cone targets based on polarization ratio of scattering center

This article starts from the high range resolution profile(HRRP), on account of difficult problems in the characteristics of the sensitivity of the HRRP and the recognition of the target of the cone type attitude, analyzes the correlation between polarization ratio of scattering center and the target attitude. Scattering center parameter estimation model is used to extract the scattering center parameters of cone targets from the wideband data, such as amplitude and location of scattering center. And the amplitude polarization ratio of the extracted scattering center parameters is calculated, so as to match the theoretical polarization ratio curve and finally obtain the attitude angle of the target. The results of numerical calculation and polarization feature extraction based on spherical cone verify the effectiveness of the method, which provides a basis for further target recognition.
