Effect of clutter on joint radar-communications system performance inner bounds

We analyze the effects of clutter on inner bounds for the performance of a joint radar-communications system. Radar returns from clutter are often characterized by a randomly fluctuating cross section. Hence, statistical methods must be employed to model the clutter and its cross-section. In this paper we consider two clutter models and analyze their effect on the inner bounds on performance of a joint radar-communications system. Bounds on performance of the joint system are measured in terms of data information rate for communications, and radar estimation information rate for the radar.
