As opposed to Airborne Early Warning and Control, whose main function is to detect and track aircraft in flight, Airborne Ground Surveillance refers to a class of military airborne radar systems intended for detecting and tracking ground targets, such as cars and slow-moving helicopters.
Air-to-air missiles, rockets, and cannons can be controlled and hostile aircraft can be located using this radar, which is employed in fighter aircraft.
Bombers utilise it to locate surface targets, both fixed and moving, as well as to navigate through and avoid hazards.
Ground Surveillance Radars (GSR) are sophisticated sensor systems that keep an eye on activity in or near sensitive infrastructure sites like airports, military bases, borders, refineries, and other crucial sectors of the economy.
The Global Airborne Ground Surveillance Radar System market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The Moving Target Indicator (MTI) software is also a part of these airborne surveillance radars. The movement of targets like trucks or ships is detected using this.
MTIs are helpful in supporting combat management both on land and in the sea setting. The Northrop Grumman AN/APY-7 radar is a part of the United States Air Force’s Boeing E-8C Joint Surveillance Target Attack Radar System.
During Operation Desert Storm, this radar tracked vehicles belonging to the Iraqi Army using its SAR and MTI capabilities.
Iraq was driven out of Kuwait by the US-led coalition’s Desert Storm operation. When coalition air power needed to be directed at these targets during conflict, information from the E-8C was especially helpful.
The detection of objects on the ground and at sea is another important function of airborne surveillance radars. It can be quite “cluttered” in both the terrestrial and maritime habitats.
The term “clutter” describes the erroneous echoes that a radar picks up when its transmissions strike objects on the surface and the ground. For instance, the sea contains wave crests, which can occasionally be rather large.
These wave crests will be detected by a radar and shown on the screen. Similar to the air, the ground is littered with a wide variety of items, including buildings, plants, and automobiles.
Small targets on the screen, such as a boat or automobile, may be obscured by bigger ones due to clutter. There are a lot of aerial surveillance radars that operate in the X-band (8.5GHz to 10.68GHz) and higher because of this.
