Multistatic Radar Placement Optimization for Cooperative Radar-Communication Systems

In this letter, we investigate a scenario where both multistatic radar and point-to-point communication systems are present with a partial or total spectrum-sharing constraint. We propose a new adaptive radar receivers placement mechanism that jointly maximizes the signal-to-interference-plus noise ratio of each communication transmitter-radar receiver channel while minimizing the geometric dilution of precision. The proposed joint approach performs well in the presence of communication interference on the radar side. In fact, the proposed approach helps to increase the capability to properly demodulate the communication data at each radar receiver resulting in the less radar measurement errors due to communication interference while enhancing the target positioning accuracy.
