Research on measurement algorithm of vector miss distance based on impulse radar

In this paper, the vector miss distance problem of moving target based on impulse radar is studied. By using the characteristic of equivalent sampling, the paper presents measurement method about time difference of each point scatter´s return signal between receiving antennas. Then the TDOA algorithm can realize space localization of each point scatter by using the time difference. Further the estimation method of vector miss distance parameter such as bias angle, obliquity is presented by constructing trajectory equation. And the localization results can realize the estimation of attitude angle. Simulation results of the proposed method indicate the validity in the parameter estimation of vector miss distance.
