Query: Sparse Transmit Array Design for Dual-Function Radar Communications by
  Antenna Selection   Dual-function radar communications (DFRC) systems have recently been proposed
to enable the coexistence of radar and wireless communications, which in turn
alleviates the increased spectrum congestion crisis. In this paper, we consider
the problem of sparse transmit array design for DFRC systems by antenna
selection where same or different antennas are assigned to different functions.
We consider three different types of DFRC systems which implement different
simultaneous beamformers associated with single and different sparse arrays
with shared aperture. We utilize the array configuration as an additional
spatial degree of freedom (DoF) to suppress the cross-interference and
facilitate the cohabitation of the two system functions. It is shown that the
use of sparse arrays adds to improved angular resolution with well-controlled
sidelobes on DFRC system paradigm. The utilization of sparse arrays in DFRC
systems is validated using simulation examples.
