Configuration Files

The SD card inserted into the SD card slot of the radar holds the hardware and software configuration files for the radar:

  • BOOT.bin holds the hardware configuration.
  • SPIProgram.elf is the radar programming executable.
  • TagDetection.elf is the main tag detection script.
  • MAC.txt is a text file used to set the MAC address of the radar.
  • settings.csv is a comma separated values file used to change network (including target IP address for the UDP messages), general, and exposed radar settings.
warning

Modification or deletion of any of the files in the SD card may result in a complete loss of proper radar operation. BOOT.bin, SPIProgram.elf, andTagDetection.elf should only be replaced in the case of updated files having been sent to you directly by Atheraxon for firmware updates.

settings.csv​

This file contains the following parameters of note:

  • IPAddress: The local or global IP address of the end point receiving the UDP stream.
  • Port: The endpoint's port.
  • UDPDownsampleRate: The factor by which the number of messages is downscalled. N (int), such that only 1 in N messages is sent.
  • x0: x position of the radar in the local coordinate system of your choice (in m).
  • y0: y position of the radar in the local coordinate system of your choice (in m).
  • z0: z position of the radar in the local coordinate system of your choice (in m).
  • azi0: azimuth orientation (in °) of the radar in the local coordinate system of your choice (θ, in the below image).
  • elev0: elevation orientation (in °) of the radar in the local coordinate system of your choice (90-φ, in the below image).

The orientation of the radar is defined in the below coordinate system, where the r vector is oriented normal to and out of the front of the radar. Positive elevation is defined as the radar aiming upward.

drawing

A few concrete examples:

  • θ=0, φ=0: The radar is aiming in the x direction and is, therefore, positioned along the (y,z) plane.
  • θ=45, φ=-10: The radar is aiming in the direction betwen x and y and is tilted downward by 10°.
