A Review of Radar System Deviation Accurate Registration Technology

Radar error registration is one of the key technologies of multi-source information fusion, which is in the process of data pretreatment, and its performance directly affects the result of subsequent fusion processing. Based on the mission requirements of error registration research, the research progress of error registration is reviewed and summarized around the spatial distribution model of radar system error and fine error registration technology in this paper, and the main research algorithms are summarized too. On this basis, the key problems to be solved are projected from three aspects: analysis of spatial distribution characteristics and model construction of system bias, fine registration technology of system bias in general scenarios, and research of error registration technology in sick scenarios. The corresponding methods and ideas are proposed to better meet the needs of multi-source information fusion and to improve the robustness, accuracy and engineering applicability of the error registration method.
