A real-time passive radar
660618716c
gainLna and gainVga not populated so insert static values for now. this needs fixing (I presume in blah2.cpp?) fixed the device check, previously it only triggered if 1 device was connected, but not 0 devices. other fixes for using pointers instead of deferenced pointers, etc. |

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.ymlfor 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
doxygenpages 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.
