Due to the influence of various factors,there exist measurement errors when radars are tracking targets.For the moving object,the process of radar measurement error is an unstable random course with equal value trend and time variance.The part of White Noise describes the Machine Heat Noise that received by radar.The method of primitive process of error analysis in time sequencer,the experimental data of recording the various error source in experiment is usually impossible to get,and it is difficult to record and separate all the error source in a test radar system.This paper,adopting combinations of linear recurrence and self-recurrence of time variance,related residual error,deals with the modeling of radar measurement errors(azimuth measurement,distance measurement and elevation measurement).It also discusses the nature of samples of estimation quantity and emulation arithmetic in modeling.Through the emulation instances which examine the white noise,the measurement errors and true value of the objects do not have the significance difference,at the same time,between the measurement errors and true value(mere measurement),the error is less than 1‰,which proves that the method presented to be feasible and effective.
