  Radar simulation is a promising way to provide data-cube with effectiveness
and accuracy for AI-based approaches to radar applications. This paper develops
a channel simulator to generate frequency-modulated continuous-wave (FMCW)
waveform multiple inputs multiple outputs (MIMO) radar signals. In the proposed
simulation framework, an open-source animation tool called Blender is utilized
to model the scenarios and render animations. The ray tracing (RT) engine
embedded can trace the radar propagation paths, i.e., the distance and signal
strength of each path. The beat signal models of time division multiplexing
(TDM)-MIMO are adapted to RT outputs. Finally, the environment-based models are
simulated to show the validation.
