基于知识辅助的高精度SAR-GMTI目标定位技术
Technology of High Accuracy SAR-GMTI Target Location Based on Knowledge-aid
摘要
Abstract
Because of the long distance,the error of position estimation of ground moving target became bigger based on the method of interferential phase,which resulted in the method was very difficult to be used.The precision of velocity and position estimation was analyzed of the GMTI method based on the interferential phase.A new method was proposed based on the knowledge-aid,which made use of road detection based on the SAR image,and the accuracy of position estimation could be increased greatly.The validity of method was validated using measured data.关键词
