Joint MIMO Communication and MIMO Radar Under Different Practical Waveform Constraints

A joint transceiver coexistence design of multiple-input multiple-output (MIMO) communication and MIMO radar is addressed under different practical waveform constraints. Without radar waveform constraints, the conventional optimal waveforms can result in large modulus variation and poor range resolution. To tackle these problems, the constant-modulus and/or similarity constraints are added in this work. The proposed constant-modulus waveform constraint is favoured by the cheap and efficient nonlinear power amplifier, and the proposed similarity constraint provides a flexible control on modulus variation, range resolution and transmit power, at the cost of a small extra computational complexity.
