Joint Design of Radar Transmit-Receive Pair in Highly Reverberating and Congested Environments

In this paper, a novel design strategy for radar transceivers, aimed at ensuring spectral coexistence with surrounding Radio Frequency (RF) emitters while improving radar performance, is presented. Specifically, the interference energy induced by the radar on each shared bandwidth is controlled. Moreover, along with an upper bound to the maximum transmitted energy, constant envelope signals are considered as probing waveform, with a similarity constraint to ensure some relevant features on the transmit signal. The design formalization results in NP-hard optimization problems, solved through iterative algorithms based on Coordinate Descent (CD) method. Finally, numerical results are provided to show the effectiveness of this new design technique.
