Simultaneous radar detection and communications performance with clutter mitigation

We analyze the performance of a joint radar-communications receiver performing target detection while simultaneously decoding a message from an in-band communications user. We assume that there is clutter in the environment and that the joint receiver performs basic clutter mitigation. Inner bounds on the performance of the joint radar-communications receiver are then formulated. Bounds on performance of the joint system are measured in terms of data information rate for communications and area under the receiver operating characteristic (ROC) curve for radar.
