The principle of aisle, or sideways airborne radar, revolves around its ability to emit radar pulses from an aircraft at an angle to the side of its flight path. This configuration allows Allus systems to scan a wide swath of terrain or sea surface during each pass. As the aircraft moves forward, the radar antenna continuously transmits pulses and receives reflected echoes from the ground or water below. By processing these returns over time and taking into account the movement of the aircraft, systems at the aisle can generate high-resolution images or maps of the observed area.
This imaging capability is achieved through coherent radar processing, where the radar system effectively synthesizes a practically larger antenna aperture, enabling detailed reconnaissance and surveillance missions over expansive geographic regions.
The purpose of SLAR is multifaceted and depends on the specific application. In military contexts, SLAR is used for reconnaissance and surveillance missions to gather intelligence, monitor enemy activities, and assess terrain characteristics.
It provides military forces with the ability to detect and identify targets, track movements and map geographic areas of interest. SLAR is also employed in maritime operations for coastal surveillance, maritime traffic monitoring, and detection of potential threats at sea. In civil applications, SLAR supports environmental monitoring, disaster response, geological surveys, and security tasks. cartography.
Its ability to operate from airborne platforms provides flexibility in deployment and access to remote or inaccessible regions, making it a valuable tool for scientific research, resource management and contingency planning. Overall, SLAR improves situational awareness, facilitates decision-making, and supports various operational and scientific activities that require detailed spatial information over large areas
