Performance Analysis of a Dynamic Programming Track Before Detect Algorithm
In high noise and clutter, target tracking techniques, such as the Kalman filter, probabilistic data association (PDA) and multiple hypothesis testing (MHT), declare detections at each measurement time. The detections are then used to estimate the target trajectory. A limitation of these methods is that much of the information contained in the measurements is discarded due to the application of...
متن کاملParameter Adjustment for a Dynamic Programming Track-before-Detect-Based Target Detection Algorithm
This paper addresses the problem of tracking a dim moving point target in a sequence of IR images. The proposed tracking system, based on the track-before-detect (TBD) approach, is designed to track and detect dim maneuvering targets from an image sequence under low SNR conditions; a dynamic programming algorithm (DPA) is used to process the frames in the sequence. This paper deals with the pra...
متن کاملCompressed Sensing Based Track before Detect Algorithm for Airborne Radars
This paper presents a novel compressed sensing based track before detect (CS-TBD) algorithm. The proposed algorithm reconstructs the whole radar scenario (direction of arrival (DOA)Doppler plane) for each range gate at consecutive scans using an improved stagewise orthogonal matching pursuit (StOMP) algorithm, resulting in a three-dimensional range-DOA-Doppler space. It then performs temporal t...
متن کاملA Track-Before-Detect Algorithm based on KA-HT
Track-before-Detect (TBD) methods have been applied in the fields of dim target detection in radar systems. The basic principle of TBD is actually the theory of multiple frame integration detection, that is, using the multiple scans data to detect the dim target by accumulation effect which make use of information about target motion trajectory to increase the target detection capability of a s...
