Abstract

Range alignment is an important step in the preprocessing of wideband radar echoes. However for the echoes of space coning target with micro-motions that only has several scatter centers, the range alignment methods available do not work well. Range alignment is the key step in the parameters estimation algorithms for wideband radar echoes of targets with micro-motions. This paper proposes a range alignment method based on the polarization scattering characteristics. The proposed method first estimates the number, locations and polarization scattering matrices of the scatter centers in the wideband radar echoes using the combing Pole Capon and Amplitude and Phase EStimation (P-CAPES) super-resolution method. Then, polarization similarities of the scatter centers in the adjacent echoes are calculated with the polarization scattering matrices and are used to range alignment. Experiments verify the effectiveness of the proposed method by using electromagnetic data.

Key words： Wideband radar Micro-motion Polarization scattering matrix Combing Pole Capon and Amplitude and Phase EStimation (P-CAPES) Range alignment
