带多普勒量测的序贯SCKF雷达目标跟踪算法
A Sequential Square Root Cubature Kalman Filter Algorithm for Radar Target Tracking with Doppler Measurement
摘要
Abstract
To improve the performance of radar target tracking under nonlinear measurements,a sequential square root cubature Kalman filter algorithm with Doppler measurement( SSCKF-D) is proposed by intro-ducing the sequential processing in square root cubature Kalman filter( SCKF) . In this algorithm a pseudo measurement is constructed to decorrelate the errors of range and range rate measurement. Based on SCKF, the measurements of bearing,elevation and range,also the pseudo measurement are sequentially processed according to the measuring accuracy. The Monte Carlo simulation indicates the improved estimation accura-cy and convergence rate of SSCKF-D by comparing with SCKF and SCKF-D. It enhances the accuracy a-bove 20% than the latter algorithm and it is more suitable for target tracking in aerospace.关键词
