This paper studies the performance of the GOSGO and GOSSO CFAR detectors [1] in clutter edge situation. The authors derive the analytic expressions of the false alarm probabilities in that situation, analyze their performances against clutter edge, and compare them with the OS, CA, GO and SO detectors. The results show that GOSGO possesses better performance than GO for countering clutter, but the performance of GOSSO is very unideal. 展开更多

A detection of static or slowly moving targets in the inhomogeneous clutter of polarimetric radar is researched and a new detector without exploiting the training set is developed, which has a good performance against the inhomogeneous clutter. The decision rule ensures the constant false alarm rate (CFAR) with respect to the disturbance covariance matrix. Numerical results show the robustness of the proposed method against the inhomogeneous clutter. © 2016 Beijing Institute of Aerospace Information. 展开更多

The probability hypothesis density(PHD),a well-known scheme for multi-target tracking in clutters,can obtain peaks of possible tracks,and its cluster-indexed method is widely accepted in further track extraction.However,the track extraction may face high risk in the case that the targets are so approached that it is hardly to discern their measurements.The concept of the distance between track sets in two adjacent times is defined and a consistency measure metric between any two peaks in two adjacent times is further proposed based on'global information',containing spatial information(topology feature)among tracks,along with the temporal information of each track.Then,a global track extraction method is proposed based on the consistency belief and four decision rules.Via the simulation comparison with the cluster-indexed method,the proposed method can avoid the track break and mistake association.©2016 Beijing Institute of Aerospace Information. 展开更多
