### Available end points:

- `/instruments/` - Will list all Instruments in the database
- `/instruments.json` - Will return all Instruments in json format
- `/instruments/<object_id>/` - Returns Instruments object with that id

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

- `title`
- `uuid`

The radar is a fully coherent, Ka band, dual-polarisation, pulse compression Doppler radar. It is currently installed on a ground fixed pedestal with a 2.4 m parabolic antenna. The radar is designed to complement the 94 GHz (3 mm) \"Galileo\" cloud radar currently operating at the Observatory for observations of cloud microphysics and climatology.",
