ORB 37 is operating in the X-Band weather and ground mapping radar developed for French C-160 Transall transport aircraft. It is derived from the ORB-31 family of radars, but is configured to fit fixed-wing aircraft, has a lower peak power, and uses a slotted flat-plate antenna.
ORB 37 carries out weather avoidance and accurate ground-mapping functions, and is fitted with an interrogation facility for beacon homing. There are two scan modes: low rate in the weather mode and at high rate when ground-mapping.
The ORB-37 has seven LRUs. These include the antenna, a transreceiver, power supply, an analog parallel peripheral interface at the operator’s station particularly suited for ground mapping, as well as a digital PPI scope on the flight deck, and flight deck and navigator station control units.
