As one of the topical research area in the field of radar, polarimetric signal processing techniques gradually receive the attention of scholars worldwide and have been widely applied in various fields. The basis of polarimetric signal processing is to acquire polarization information. In this paper, the research statuses of several relevant key aspects are reviewed, including polarization information acquisition, polarization diversity and coding, polarization anti-interference/clutter, polarization detection, and classification and identification of targets. Finally, the problems faced by radar polarimetry techniques are concluded, and the prospects of future development of the techniques are discussed.
