Track-before-detect procedures for detection of extended object
In this article, we present a particle filter (PF)-based track-before-detect (PF TBD) procedure for detection of extended objects whose shape is modeled by an ellipse. By incorporating of an existence variable and the target shape parameters into the state vector, the proposed algorithm performs joint estimation of the target presence/ absence, trajectory and shape parameters under unknown nuis...
متن کاملA switching algorithm for tracking extended targets
Tracking extended objects like humans in crowded environments is one of the challenges in mobile robotics. Several characteristics must be taken into consideration when evaluating the performance of such a tracking algorithm — e.g. accuracy, the need for computation time and the ability to deal with complex situations like crossing targets. In this paper two different algorithms for tracking ex...
متن کاملTrack-Before Detect Methods in Tracking Low-Observable Targets: A Survey
In detection and target tracking applications, low-observable targets are defined as those that deliver measurements for which the sensor responses have a value of SNR lower than 10dB. Tracking of low-observable targets is best performed employing the approaches known as trackbefore-detect (TBD). The proper TBD approaches combine signal processing and tracking so that detection and track confir...
متن کاملA Novel Track-Before-Detect Algorithm for Weak Target
In this paper, a novel track-before-detect algorithm is proposed for weak target with low signal to noise ratio. Multi-sensor information combining with trackbefore-detect technology is used to improve the signal to noise ratio. According to frame sequences of each sensor, Rao-Blackwellized particle filter, which is a clever combination of the Kalman filter and the standard particle filter, is ...
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...
