A real-time radar which can support various SDR platforms. See a live instance at http://radar4.30hours.dev.

• Currently only support for the SDRplay RSPDuo.
• 2 channel processing for a reference and surveillance signal.
• Designed as a passive radar, but can also work as an active radar.
• Outputs delay-Doppler maps to a web front-end.
• Record raw IQ data by pressing spacebar on the web front-end.
• Saves delay-Doppler maps in a json array.

The build environment consists of a docker-compose.yml file running the following services;

• The radar processor responsible for IQ capture and processing.
• The API middleware responsible for reading TCP ports for delay-Doppler map data, and exposing this on a REST API.
• The web front-end displaying processed radar data.

• Install docker and docker-compose on the host machine.
• Clone this repository to some directory.
• Install SDRplay API to run service on host.
• Edit the config.yml for desired processing parameters.
• Run the docker-compose command.

sudo git clone http://github.com/30hours/blah2 /opt/blah2
cd /opt/blah2
vim config/config.yml
./lib/sdrplay-3.0.7/SDRplay_RSP_API-Linux-3.07.1.run --tar -xvf
./lib/sdrplay-3.0.7/install.sh
sudo docker network create blah2
sudo systemctl enable docker
sudo docker compose up -d

The radar processing output is available on http://localhost:49152.

• See doxygen pages hosted at http://doc.30hours.dev/blah2.

• Add a tracker in delay-Doppler space.
• Add ADS-B overlay on the delay-Doppler map.
• Support for the HackRF and RTL-SDR using a front-end mixer to sample 2 RF channels in 1 stream.

• If the SDRplay RSPduo does not capture data, restart the API service (on the host) using sudo systemctl restart sdrplay.api.

Pull requests are welcome - especially for adding support for a new SDR.
