Adaptive probability hypothesis density filter for multi-target tracking with unknown measurement noise statistics

Abstract: Under the Gaussian noise assumption, the probability hypothesis density (PHD) filter represents a promising tool for tracking a group of moving targets with a time-varying number. However, inaccurate prior statistics of the random noise will degrade the performance of the PHD filter in many practical applications. This paper presents an adaptive Gaussian mixture PHD (AGM-PHD) filter for the multi-target tracking (MTT) problem in the scenario where both the mean and covariance of measurement noise sequences are… Show more

“…17 The KF-based and its improved methods are the preferred and widely used techniques. 18ā€“21 However, there are some disturbances of the sensor measurements and driving environment, 22 which will produce a bad robustness or tracking accuracy within some complex environment. To restrict the effect of exogenous disturbances, the H āˆž theory is the preferred tool.…”

“…In principle, the GM-PHD filter does not provide the trajectory of a target, so several methods have been proposed to achieve data association and track management [10,11]. Since the performance of the GM-PHD filter could be degraded (possibly significantly) in a highly cluttered environment, some studies have focussed on tracking targets in a highly cluttered environment [12,13]. In addition, the occurrence of miss detection can also degrade the tracking performance.…”
