<p>Due to their rapid
technological advancement, mobile sensors such as unmanned aerial vehicles (UAVs) are
seeing growing application in the area of multi-target tracking and identity management
(MTIM). For efficient and sustainable performance of a MTIM system with mobile
sensors, proper algorithms are needed to both effectively estimate the
states/identities of targets from sensing data and optimally guide the mobile sensors based
on the target estimates. One major challenge in MTIM is that a target may be
temporarily lost due to line-of-sight breaks or corrupted sensing data in cluttered
environments. It is desired that these targets are kept tracking and identification, especially
when they reappear after the temporary loss of detection. Another challenging task
in MTIM is to correctly track and identify targets during track coalescence,
where multiple targets get close to each other and could be hardly distinguishable.
In addition, while the number of targets in the sensors’ surveillance region is
usually unknown and time-varying in practice, many existing MTIM algorithms assume
their number of targets to be known and constant, thus those algorithms could not
be directly applied to real scenarios.</p>
<p>In this research, a set of
solutions is developed to address three particular issues in MTIM that involves the
above challenges: 1) using a single mobile sensor with a limited sensing range to
track multiple targets, where the targets may occasionally lose detection; 2) using a
network of mobile sensors to actively seek and identify targets to improve the accuracy of
multi-target identity management; and 3) tracking and managing the identities of an unknown and
time-varying number of targets in clutter.</p>
