Abstract：In order to improve the accuracy of the radar registration method in the process of large error primary radar measurement,taking the track data of the broadcast automatic correlation monitoring sys-tem as the true value,the characteristics of the primary radar error distribution are analyzed,and a real-time radar registration method is proposed based on the improved track tracking filter.This method is in-tended to improve the bias function in the variable structure interactive multi-model algorithm(EMA-IMM)based on the expected increase model by adopting the iterative nearest point method(RANSAC-ICP)of random sampling consistency in point cloud registration method,effectively reducing the influence of random errors in the registration process,obtaining the optimal bias parameters,and improving the ac-curacy of large error primary radar registration.The results show that the average absolute error of pitch Angle and azimuth Angle can be reduced to 0.04° and 0.07° respectively,and this provides a new method for radar system error registration.
