[en] In this paper, we propose an attractive method to
jointly design discrete phase radar sequence and receive filter
bank with the aim of enhancing Signal to Interference and Noise
Ratio (SINR) in a cognitive radar system. Towards this, we
consider maximizing the worst case SINR at the output of the
filter bank when transmitting M-ary Phase Shift Keying (MPSK)
sequences, an exercise hitherto not considered. This maximization
results in a max-min optimization problem that is multi-variable
and non-convex, where we propose an efficient algorithm based
on the Coordinate Descent (CD) framework to address it. The
gains demonstrated by the proposed algorithm over the state of
the art as well as its discrete phase property render the designed
sequences attractive for hardware implementation while enabling
efficient utilization of transmit power.
