I am trying to obtain the Range doppler map for a human being in MATLAB, using a complete system based simulation for FMCW radar.
However, the phased.RadarTarget block only acts as a point target. I am looking for something like an extended target (sphere, ellipsoid etc) to mimic the human cadence. Can someone guide me which app, toolbox I can use for this.
Thanks!

Hi Easha,
From what I understand, the goal is to find on which app or toolbox can be used to model an extended target, such as a human with cadence, for the FMCW radar simulation. As you have worked with the phased.RadarTarget block in MATLAB's Phased Array System Toolbox which only acts as a point target, which is insufficient for simulating.
You can use the same Phased Array System Toolbox. The toolbox provides several options to model extended targets with different shapes and movement patterns.
Here's an approach you can follow:
  1. Create a Radar System: Set up your FMCW radar system using the phased.FMCWWaveform and phased.ReceiverPreamp objects.
  2. Define the Target: Use the phased.RadarTarget object to model the extended target to Specify the shape and movement characteristics of the target to mimic the human cadence.For example, you can use the phased.RadarTarget('Model', 'Extended') object to create a sphere-shaped target as you said.
  3. Configure the Target Parameters: Set the properties of the phased.RadarTarget object to define the size, position, and motion of the target. You can specify the target's position using the Position property and its motion using the Velocity property.
  4. Generate the Radar Return: Use the step function of the phased.RadarTarget object to generate the radar return signal based on the radar system parameters and the target properties.
Attached below are some documentation links that you may find helpful:
