A Track-Before-Detect Algorithm based on KA-HT

چکیده
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 system. This paper presents a knowledge-aided Hough transform (KA-HT) method for TBD to detect dim target in low SNR environments, which make full use of the information in three-dimensional range-Doppler-frame space.

Parameter 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...

Compressed 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...

Real radar data containing a small manoeuvring boat in sea clutter was processed using a grid based finite difference implementation of continuous-discrete filtering. An examination was undertaken to determine the appropriate dynamic, target amplitude and clutter amplitude models which should be utilized to allow the successful application of Track Before Detect techniques (TkBD). Both two dime...
