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!

fmcw-mimo-radar-simulation's Issues

Undefined function `rcsellipsoid` in `FMCW_sim_v4.m` and CVX toolbox version in `FMCW_simulation.m`

Hi Emre Kurtoglu,

Firstly, thank you for providing such a comprehensive simulation tool for FMCW MIMO radar. I have encountered a couple of issues while running the scripts and would appreciate your assistance.

Issue 1: Undefined function rcsellipsoid in FMCW_sim_v4.m
When running the FMCW_sim_v4.m script, MATLAB throws an error indicating that the function rcsellipsoid is undefined. This occurs at line 147, where the function is called. Here is a screenshot of the error:

Could you please check if this function is missing from the repository or provide guidance on how to define or obtain this function?

Issue 2: CVX toolbox dependency in FMCW_simulation.m
Additionally, I noticed that the FMCW_simulation.m script uses the CVX toolbox. It would be helpful to include a note in the README file specifying its version and providing installation instructions or a link to the CVX toolbox.

Thank you very much for your support and contributions to the community. Looking forward to your response.

Best regards,
zhenyu

Questions about the different distance resolutions between MUSIC and 3D-FFT

Because both MUSIC and 3D-FFT use 2D-FFT to measure distance, then why are the distance resolutions of the two different?
