Airborne Ground Surveillance
Airborne ground surveillance (AGS) refers to a class of military airborne radar system (Surveillance aircraft) used for detecting and tracking ground targets, such as vehicles and slow moving helicopters, as opposed to Airborne early warning and control, whose primary role is detecting and tracking aircraft in flight. Antenna beam width should be very small to enhance resolution. This antenna size limitation demands high frequency (GHz range) of operation, to be operated in this mode. AGS radar is typically a medium or low power radar. It includes both maritime and land surveillance. Today, UAVs perform this operation, which often uses optical aids for surveillance.

Tupolev Tu-204
The Tupolev Tu-204 () is a twin-engined medium- range narrow-body jet airliner capable of carrying 210 passengers, designed by Tupolev and produced by Aviastar-SP and Kazan Aircraft Production Association. First introduced in 1995, it was intended to be broadly equivalent to the Boeing 757, with slightly lower range and payload, and had competitive performance and fuel efficiency in its class. It was developed for Aeroflot as a replacement for the medium-range Tupolev Tu-154 trijet in the 1990s. The latest version, with significant upgrades and improvements, is the narrow-body Tu-204SM, which made its maiden flight on 29 December 2010. In April 2022, United Aircraft Corporation (UAC) announced plans to assemble 70 Tu-214s by 2030. However, in early 2024, Aeroflot expressed intention to transfer its order for fleets exclusively to next-generation MC-21 jets. The rejection of the Tupolev has various reasons, including no two-member cockpit, and also the evacuation ramps and ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alliance Ground Surveillance

Intelligence, Surveillance, Target Acquisition, And Reconnaissance
ISTAR stands for intelligence, surveillance, target acquisition, and reconnaissance. In its macroscopic sense, ISTAR is a practice that links several battlefield functions together to assist a combat force in employing its sensors and managing the information they gather. Information is collected on the battlefield through systematic observation by deployed soldiers and a variety of electronic sensors. ''Surveillance'', ''target acquisition'' and ''reconnaissance'' are methods of obtaining this information. The information is then passed to intelligence personnel for analysis, and then to the commander and their staff for the formulation of battle plans. Intelligence is processed information that is relevant and contributes to an understanding of the ground, and of enemy dispositions and intents. Intelligence failures can happen. ISR (Intelligence, surveillance and reconnaissance) ISR is the coordinated and integrated acquisition, processing and provision of timely, accurat ...

JLENS
The Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System, or JLENS (colloquially, Spy Balloon), was a tethered aerial detection system designed to track boats, ground vehicles, cruise missiles, manned and unmanned aircraft (airborne early warning and control), and other threats. The system had four primary components: two tethered aerostats which utilized a helium/air mix, armored mooring stations, sophisticated radars, and a processing station designed to communicate with anti-missile and other ground and airborne systems. Each system was referred to as an "orbit", and two orbits were built. The Army-led joint program which fielded JLENS was designed to complement fixed-wing surveillance aircraft, saving money on crew, fuel, maintenance and other costs, and give military commanders advance warning to make decisions and provide notifications. Following cost overruns, underperformance, declining support in Congress, and public scrutiny following a snapped tether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tethered Aerostat Radar System
The Tethered Aerostat Radar System (TARS) is an American low-level airborne ground surveillance system that uses aerostats (moored balloons) as radar platforms. Similar systems include the EL/M-2083 and JLENS. System The aerostats used in the TARS system are large fabric envelopes filled with helium that can rise to an altitude of while tethered by a single cable. The largest lifts a 1000 kg payload to an operating altitude providing low-level, downward-looking radar coverage. The aerostat consists of four major parts or assemblies: the hull and fin, windscreen and radar platform, airborne power generator, and rigging and tether; they are kite balloons obtaining aerodynamic lift from relative wind and buoyancy from being Lifting gas, lighter than air. The hull of the aerostat contains two parts separated by a gas-tight fabric partition. The upper chamber is filled with helium and provides the aerostat's lifting capability. The lower chamber of the hull is a pressurized a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Raytheon Sentinel
The Raytheon Sentinel is a retired airborne battlefield and ground surveillance aircraft formerly operated by the Royal Air Force (RAF). While based on the Bombardier Global Express ultra long-range business jet, the prime contractor for the Sentinel was the American defence firm Raytheon, which supplied most of the mission systems and performed the integration work. Originally known as the ASTOR (Airborne STand-Off Radar) programme, procurement of the type started during 1999. Following its delivery in 2007, the Sentinel fleet was operated by an RAF squadron manned by both air force and army personnel. The Sentinel was interoperable with other allied systems such as JSTARS and the NATO Alliance Ground Surveillance (AGS) system. Sentinels were deployed overseas on multiple occasions, such as in support of the British Army in Afghanistan, coalition forces in Libya, and to assist French forces deployed in Mali. The type also saw smaller-scale deployments in Ghana and even domes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airborne Radar System
An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack aircraft. AEW&C units are also used to carry out aerial surveillance over ground and maritime targets, and frequently perform battle management command and control (BMC2). When used at altitude, the radar system on AEW&C aircraft allows the operators to detect, track and prioritize targets and identify friendly aircraft from hostile ones in real-time and from much farther away than ground-based radars. Like ground-based radars, AEW&C systems can be detected and targeted by opposing forces, but due to aircraft mobility and extended sensor range, they are much less vulnerable to counter-attacks than ground systems. AEW&C aircraft are used for bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
