Detection and Estimation of Parameters of a Random Process Set in Multi-Scanning Radar Observation Based on the "Track - Before- Detect" Methods

In this paper we consider methods of long-term (multi-scanning) radar observation based on "track-before-detect" technologies. We analyze a two-stage procedure for joint detection-estimation of trajectories. In the paper we prove the advisability of the use of a relatively simple a priori model of target movement at the traj ectory detection stage. We show that it is possible to use a more complex model at the stage of trajectory parameters estimation. The analysis of the well-known block algorithm for estimating trajectory parameters using the least squares method is carried out. We offer a methodology for testing the accuracy of traj ectory parameters measurements when implementing the block method of multi-scanning observation.
