Joint Beamforming and Association Design for MIMO Radar
A critical task of a radar receiver is data association, which assigns radar
target detections to target filter tracks. Motivated by its importance, this
paper introduces the problem of jointly designing multiple-input
multiple-output (MIMO) radar transmit beam patterns and the corresponding data
association schemes. We show that the coupling of the beamforming and the
association subproblems can be conveniently parameterized by what we term an
ambiguity graph, which prescribes if two targets are to be disambiguated by the
beamforming design or by the data association scheme. The choice of ambiguity
graph determines which of the two subproblems is more difficult and therefore
allows to trade performance of one versus the other, resulting in a
detection-association trade-off. This paper shows how to design both the beam
pattern and the association scheme for a given ambiguity graph. It then
discusses how to choose an ambiguity graph achieving close to the optimal
detection-association trade-off
