Error Analysis of Fast-moving Target Geo-location in Wide Area Surveillance Ground Moving Target Indication Mode

As an important mode in airborne radar systems, Wide Area Surveillance Ground Moving Target Indication (WAS-GMTI) mode has the ability to monitor a large area in a short time, so that detected moving targets can be quickly located. In a real environment, however, many factors introduce considerable errors into the locations of moving targets. In this study, a fast-location method, based on the characteristics of moving targets in WAS-GMTI mode, was utilized. In order to improve the performance of target location, those factors that introduce location errors were analyzed, and moving targets were relocated. The analysis of those factors was proven to be reasonable in simulations and in real-data experiments.
