Cymbeline FA 15
Cymbeline FA 15 (Field Artillery, No 15) is a mortar detection, location and counter-battery artillery fire adjustment radar using a magnetron generator operating in X-band. The antenna consists of a single curvature parabolic reflector illuminated from beneath by a triplecone Foster scanner. The system produces a pencil beam scanning in azimuth. The reflector folds down flat for transport.
A Cymbeline radar is predominantly solid-state, with the CRT, magnetron, and thyratron being the sole thermionic components. It can be located on the trailer of a tracked transport vehicle or on the stern of an armored vehicle, which makes it possible to move it to an ideal location for a given operation.
There were 3 main variants:
- Cymbeline Mark 1: Original production trailer-mounted version now supplanted by Cymbeline Mark 3;
- Cymbeline Mark 2: Cymbeline Mark 1 repackaged for installation on the FV-432 armoured personnel carrier;
- Cymbeline Mark 3: Radically improved and upgraded variant of Cymbeline Mark 1. Major improvements include fully solid-state electronics, and an active phased array antenna that may be mounted on a telescope attachment.
Cymbeline replaced the Green Archer as the mortar locating radar of the British Army.
