What does the term "Longbow" mean in the military?

The "Longbow Apache" is due to the replacement of the "Longbow" millimeter wave radar. The principle prototype of the radar weighed 226 kilograms, and the production model has been reduced to l72 kilograms. The radar antenna is mounted on the top of the main rotor shaft, and can carry out a 360-degree all-round continuous scanning, but also can focus on a sector scanning. "The Longbow's radar waveform has short pulses, an undetectable waveform, small side flaps and a certain degree of frequency shortening, making it difficult to be intercepted or interfered with. When the helicopter is under the cover of complex terrain, this kind of radar wave can go through the bad atmosphere and find the target camouflaged in the ground miscellaneous weeds which cannot be found by the on-board infrared equipment, and can compare the characteristics of the target signal detected by the radar with the data base through the target detection and classification equipment, and then rank the threat level to the carrier in order. When tracking and targeting, the radar is not only fast (70 per cent less targeting time than current targeting methods), but can also target multiple targets. "The Longbow radar has multiple modes of operation, detecting airborne targets in the air-ground mode, but not ground targets in the air-air mode. An AH-64D equipped with the Longbow radar can provide airborne surveillance for an entire strike squadron. "The Longbow radar also has a terrain tracking capability, which is typically used when the pilot's night vision equipment and night vision goggles (NVGs) are not adequate.
