  A multistatic radar set-up is considered in which distributed receive
antennas are connected to a Fusion Center (FC) via limited-capacity backhaul
links. Similar to cloud radio access networks in communications, the receive
antennas quantize the received baseband signal before transmitting it to the
FC. The problem of maximizing the detection performance at the FC jointly over
the code vector used by the transmitting antenna and over the statistics of the
noise introduced by backhaul quantization is investigated. Specifically,
adopting the information-theoretic criterion of the Bhattacharyya distance to
evaluate the detection performance at the FC and information-theoretic measures
of the quantization rate, the problem at hand is addressed via a Block
Coordinate Descent (BCD) method coupled with Majorization-Minimization (MM).
Numerical results demonstrate the advantages of the proposed joint optimization
approach over more conventional solutions that perform separate optimization.
