Precision Analysis of Direction-Finding Location Considering Time Synchronization Error in Fire-Control Radar Net

摘要

As is well known,the position of jammer could be located by spatially distributed measurement points from passive angle measurements.Generally,such angle measurements include the horizontal bearing (azimuth angle) and the vertical bearing (elevation angle).Based on direction-finding location method,an efficient solution for jammer location by two spatially distributed radar stations in fire-control radar net is presented.Extraordinarily,the system time synchronization error is originally discussed here. An innovative mathematics model of the location precision is presented and facilitates the system location performance analysis,and formulae are provided for the modeling.Performance evaluation results are presented for defined condition.
