README.md

blah2

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

Features

Support for the SDRplay RSPDuo, USRP (only tested on the B210) and HackRF.
2 channel processing for a reference and surveillance signal.
Designed to be used with external RF source (for passive radar or 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

Building the code using the following instructions;

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/config.yml for desired processing parameters.
Run the docker-compose command.

sudo git clone http://github.com/30hours/blah2 /opt/blah2
cd /opt/blah2
sudo chown -R $USER .
sudo chmod a+x ./lib/sdrplay-3.14.0/SDRplay_RSP_API-Linux-3.14.0.run
sudo ./lib/sdrplay-3.14.0/SDRplay_RSP_API-Linux-3.14.0.run --tar -xvf -C ./lib/sdrplay-3.14.0
cd lib/sdrplay-3.14.0/ && sudo ./install_lib.sh
sudo docker network create blah2
sudo systemctl enable docker
sudo docker compose up -d --build

Alternatively avoid building and use the pre-built Docker packages;

sudo docker pull ghcr.io/30hours/blah2:latest
vim docker-compose.yml
--- build: .
+++ image: ghcr.io/30hours/blah2:latest
sudo docker compose up -d

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

Documentation

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

Future Work

Add a tracker in delay-Doppler space.
Support for the HackRF and RTL-SDR using a front-end mixer to sample 2 RF channels in 1 stream.
Support for the Kraken SDR.
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 the script sudo ./script/blah2_rspduo_restart.bash.

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 - contact me for more info.
