Nonlinear Waveform Sensing for Cognitive Radar Based on Reinforcement Learning

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Cognitive radar automatically adjusts its waveform via ceaseless interaction with the environment and learning from the experience. Compared with the linear frequency modulation (LFM) that has been commonly adopted in cognitive radars, the nonlinear FM ...

Energy Sharing and Performance Bounds in MIMO DFRC Systems: A Trade-Off Analysis

IET Signal Processing
It is a fundamental problem to analyze the performance bound of multiple-input multiple-output dual-functional radar-communication systems. To this end, we derive a performance bound on the communication function under a constraint on radar performance ...
