| Abstract: | This paper explores a method for detecting and tracking small and faint targets in high-cluster environments. Based on the technology of conventional radar digital detection, the new method spreads the pointed targets to lines or planes. In view of the moving target properties and dimension changing of spread target, stochastic noise and high clutter are eliminated by the rules of the targets movements and their substantialized dimensions. The precise detection and stable tracking of targets are carried out by the sliding-window method and m/N detection criterion together with track-matching algorithm. A simulation experiment has confirmed the feasibility of the method. |
