Mutual coupling analysis for colocated MIMO radar applications using CEM modeling

In this paper, mutual coupling is analyzed from calculations of the active voltage standing wave ratio (VSWR) and the reflected power of a coherent colocated Multiple Input-Multiple Output (MIMO) radar when random phase coded waveforms are transmitted. The scattering matrices of a colocated MIMO radar antenna array were obtained from computational electromagnetic (CEM) modeling methods. A Monte Carlo simulation of 10,000 realizations was used to produce time-varying random phase codes and estimate distributions for the VSWR and reflected power.
