|
|
|
|
|
A real-time radar which can support various SDR platforms.
|
|
|
|
|
|
|
|
|

|
## Features
|
|
|
|
|
|
|
|
|
|
- Currently only support for the [SDRplay RSPDuo](https://www.sdrplay.com/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.
|
|
|
|
|
|
|
|
|
|
## 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.
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
- A CFAR detector has not yet been implemented.
|
|
|
|
|
- Support for the HackRF and RTL-SDR using front-end mixer to sample 2 RF channels in 1 stream.
|
|
|
|
|
- Occasional segmentation fault from a mutex issue.
