Fast Track Confirmation for Multi-Target Tracking with Doppler Measurements
Xuezhi Wang, Darko Mušicki, Richard Ellem · 2007
In this paper, a one-point track initiation method is derived for conventional target tracking systems where noisy sensor measurements of both target position and Doppler are available. Tentative tracks are initiated using position measurements from every single scan and the associated Doppler measurements are incorporated to reduce the velocity uncertainties of these initiated track states. The proposed track initiation method is capable of reducing the computational requirements of the system quadratically compared to the classical two-point method when false measurements are present. We further demonstrate that a tracking system which incorporates Doppler measurements both for track initiation and measurement-to-track association can greatly reduce the number of false tracks that are generated and provides greater flexibility for confirming true tracks without sacrificing the system's performance in terms of the number of confirmed false tracks. As a consequence, a tracking system that incorporates the proposed method will exhibit a much shorter true track confirmation delay than a similar system based on the standard approach.
