Abstract

In this paper

the miss distance measurement problem for targets in rectilinear motion and with constant accelerations is studied.A miss distance measurement equation is derived.Based on it

the meaurement problem is represented as the nonlinear least square fitting of Doppler frequency time series in the course of interceptions

and then nonlinear optimizing algorithms are discussed for solving it.Simulations show that the new method for Doppler miss distance measurement can eliminate the systematic errors of methods based on a uniform rectilinear motion model.
