But by default the DOA software is the one that will run on boot. To change to the passive radar code, connect a monitor and keyboard (or SSH in), and edit `start.sh` in the home folder. You will need to comment out the DOA code run lines, and uncomment the passive radar lines. +The passive radar code works on both Kraken and Kerberos devices. Make sure that you set a preconfig file that is prefixed with "pr_" for either device. On the Pi 4 image, a "pr_" fixed preconfig is already set by default. (See further below for an explanation on the different "pr_" preconfig files) + # Passive Radar Active radar systems emit a radio pulse towards a target such as an aircraft and wait for the reflection of that pulse to return. In contrast, a passive radar system emits no signals. Instead, it makes use of already existing powerful transmitters, such as broadcast FM, TV and mobile phone towers. |
