FMCW-MIMO-Radar-Simulation

This repository is a simulation of frequency modulated continuous wave (FMCW), multiple input multiple output (MIMO) radars.

FMCW_simulation.m is the main script which creates point targets and estimates their range, velocity and angle information.

FMCW_sim_v3.m is the main script which reads 3-D coordinates of human skeleton joints captured by Kinect v2 device, and extracts the raw radar data cube (RDC) and plays range-Doppler maps, and outputs the micro-Doppler spectrogram. For more information about the data capture and skeleton extraction using Kinect, check out the Kinect repository. This script is still under development!
