A Two-Level Estimation Approach for a Radar System

In a radar surveillance system, both non-maneuvering and maneuvering conditions are usually existed during the tracking process. The computation of a radar system is complicated to track multiple maneuvering targets in real time. In order to assure the tracking accuracy in a tracking, a new estimation approach for a radar system is developed in this paper. The major concept of this approach is that the system uses two-level estimation algorithm based on Kalman filter equations in a radar tracking system. In this paper, we convince that the new estimator can track maneuvering targets well.
