# 3lips

Coordinate registration for multi-static radar using ellipse intersections. Not a dating app.

## Features

- Provides a JSON API for geolocation of targets given [blah2](http://github.com/30hours/blah2) radar nodes.
- Uses a [CesiumJS](http://github.com/CesiumGS/cesium) web front-end to visualise data.
- Ability to compare a number of algorithms for coordinate registration.

## Usage

- Install docker and docker-compose on the host machine.
- Clone this repository to some directory.
- Run the docker compose command.

```bash
sudo git clone http://github.com/30hours/3lips /opt/3lips
sudo docker compose up -d —build
```

The API front-end is available at [http://localhost:49156](http://localhost:49156).

## Method of Operation

The association uses the following algorithm:

- ADS-B associator will associate the highest SNR target within some delay and Doppler boundary around the truth.

The coordinate registration uses 1 of the following algorithms:

- 

The system architecture is as follows:

- The API server and HTML pages are served through a [Flask](http://github.com/pallets/flask) in Python.
- An initial API request with a new set of parameters (algorithms or radar nodes) will add these parameters to a common processing loop. This is so fair comparisons can be made between these parameters on the same input data.
- A set of API parameters will continue to be processed unless there is no API call in some specified time - see *main.py* to update. This allows the latest geolocation to be provided, rather than adding to the processing loop and waiting for the update from the next time increment.

## Future Work

- Implement an association algorithm that is not reliant on ADS-B truth.
- Add a variety of methods for solving the ellipse/ellipsoid intersection.
- Choose to use detection or track data from each radar.
- Long term plots to show metrics such as 2D location accuracy to ADS-B, number of aircraft tracked, etc.
