A novel approach, which can handle ambiguous data from weak targets, is proposed within the randomized Hough transform track-before-detect (RHT-TBD) framework. The main idea is that, without the pre-detection and ambiguity resolution step at each time step, the ambiguous measurements are mapped by the multiple hypothesis ranging (MHR) procedure. In this way, all the information, based on the relativity...
The high pulse repetition frequency (HPRF) mode is widely adopted in the airborne pulse Doppler (PD) radar system, which results in problem that the range measurement of target is ambiguous. In this paper, a particle filter (PF) based method is proposed for target tracking with the HPRF radar in clutter. The proposed method makes full use of the PF that each particle represents a possible target state,...
