Cognitive Radar Network: Cooperative Adaptive Beamsteering for Integrated Search-and-Track Application
Abstract
Cognitive radar (CR) is a paradigm shift from a traditional
radar system in that previous knowledge and current
measurements obtained from the radar channel are used
to form a probabilistic understanding of its environment.
Moreover, CR incorporates this probabilistic knowledge into
its task priorities to form illumination and probing strategies,
thereby rendering it a closed-loop system. Depending on the
hardware’s capabilities and limitations, there are various degrees
of freedom that a CR may utilize. Here we concentrate on spatial
illumination as a resource, where adaptive beamsteering is used
for search-and-track functions. We propose a multiplatform
cognitive radar network (CRN) for integrated search-and-track
application. Specifically, two radars cooperate in forming a
dynamic spatial illumination strategy, where beamsteering
is matched to the channel uncertainty to perform the search
function. Once a target is detected and a track is initiated, track
information is integrated into the beamsteering strategy as part of
CR’s task prioritization.
