Analysis of linearization effect of radar measurements results on accuracy of estimations of state vector of target

Annotations languages:

The method of improvement of estimations of state vector at use of a method of linearization of radar measurement results is received for a two-dimensional case. It is shown, that the correction eliminating a bias of an estimation of state vector of a target caused by application of a method of linearization, depends on target radial range, azimuth and azimuth measuring errors of a target. On the basis of statistical simulation accuracy of target trajectory parameter filtering is analysed at use of the improved model of state vector of a target.
Keywords: radar observation, linearization, target trajectory parameter filtering
