Radar Range Doppler Map Output Data

The range doppler map corresponds to one type of possible processing of the radar raw response. It is a result of the processing of one dimension of the signal.

The radar sensor processes the input wave and is then able to provide a .txt file corresponding to the data of a complex range-Doppler map that gives the relative position and speed of the target object.

One complex range-Doppler map (meaning one .txt file) is generated per mode for each simulation time step.

Figure 1. Range Doppler Map File Example

The output structure of the .txt result file is the following:

• Header:
  1. Number of Tx and Rx Antennas
     Note: If the mode for which the .txt file is generated is simultaneous [Beta Feature], the number of Tx antennas is followed by the letter "S".

     

  2. Number of pixels of the Doppler scale (abscissa axis)
  3. Number of pixels of the Range scale (ordinate axis)
  4. IDs of the antennas played in the output: list of the Tx IDs, then list of the Rx IDs
  5. Min and Max of Doppler scale (in m/s)
  6. Min and Max of Range scale (in m)
• Following lines: Complex Value [real part] [imaginary part]
