blah2

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

blah2 example display

Features

  • Support for the SDRplay RSPDuo and USRP (only tested on B210).
  • 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.

Services

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.

Usage

  • 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-3.12.1/SDRplay_RSP_API-Linux-3.12.1.run --tar -xvf -C ./lib/sdrplay-3.12.1
./lib/sdrplay-3.12.1/install_lib.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.

Documentation

Future Work

  • 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.
  • Support for using 2 HackRF boards with clock synchronisation.
  • Add automated Docker image builds on GHCR.
  • Add SoapySDR support for the C++ API to include a wide range of SDR platforms.

FAQ

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

Contributing

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

  • Currently have an issue where the USRP B210 is timing out after 5-10 mins and crashes the code. Convinced it's an issue with my usage of the API - email me for more info.
