ELM-2221

ELM-2221 - STGR (Search Track & Guidance/Gunnery Radar) is operating in the X- and Ka-band fire control radar.

The radar uses a transmitter fitted with a Traveling Wave Tube (TWT) and a Cassegrain antenna. The dual-band version uses the Ka-band for very accurate tracking, and the X-band to illuminate the aim for semi-active missiles.

The radar may also be delivered as single-band radar operating in X-band only. It got the designator ELM-2221X then. Each configuration includes TV or TV+IR package.
