Gabbiano radar sensing product

Gabbiano is an X-band surveillance radar family from Leonardo's Electronics Division, designed for patrol and surveillance on land and at sea in all weather conditions. It is a lightweight airborne radar sensor with synthetic aperture radar (SAR) and inverse SAR (ISAR) imaging, built for unmanned aerial vehicles as well as fixed-wing and rotary-wing manned aircraft.

The family has two basic configurations, T20 and T200 Power, each available with a nose-mounted antenna giving a coverage of +/-90 degrees or a belly-mounted antenna giving 360 degrees. Several antenna sizes are offered: 29 to 70 inches for the belly antenna and 12 to 25 inches for the nose antenna. The T20 is the configuration intended for platforms with tight weight and space limits, such as UAVs and small manned aircraft, because it runs from a single 28 Vdc source and has low power consumption and low probability of intercept capability.

The radar covers several modes. Spot and strip SAR give sub-meter resolution over wide swaths, and a ground moving target indication mode detects vehicles in motion. At sea, air-to-surface search with track-while-scan (more than 200 targets) is combined with ISAR to classify intercepted targets, plus sea moving target indication and SART modes for search and rescue. Maritime surveillance reaches up to 220 NM. Air-to-air mode detects moving targets in the air, and navigation aid modes include ground mapping, terrain avoidance, weather and beacon (SART, SST-181X and DO-172 standards supported). Electronic counter-countermeasures include frequency agility and jammer avoidance.

For integration, the weight ranges from 28 kg to 62 kg depending on antenna and transmitter, and the unit is air cooled. The T20 has a solid-state power amplifier with average transmitted power above 20 W, a transmitter front end of about 340 x 257 x 130 mm, an input power of 450 W from a single 28 Vdc source and an MTBF of 1,600 hours. The T200 uses a travelling-wave-tube transmitter with average power of 200 W, a transmitter of about 280 x 315 x 338 mm, input of 305 W at +28 Vdc and 1200 VA at 115 V 400 Hz, and an MTBF of 900 hours. Interfaces are Ethernet, MIL-STD-1553B, ARINC 429, ARINC 419, RS422, RS232 and USB. A dual-channel digital receiver and a programmable waveform generator allow additional modes through software updates, and the T20 can be controlled stand-alone from a dedicated control panel with an optional IFF antenna.

Applications include homeland security and border protection, exclusive economic zone protection, environmental surveillance such as oil spills, maritime patrol, search and rescue, combat search and rescue, and support to special forces operations by day or night.
