SCORAL DE LA SURCE “generally refers to the process in radar systems where the radar alternates between two operational modes: tracking mode and scan mode. Their future positions. New targets or threats.
A scanner, in a broader sense, refers to a device or instrument used to systematically scan or explore an area, object or environment to gather information. In radar and other sensor systems, a scanner generally refers to the mechanism or component responsible for achieving the sensor’s field of view or beam over a specific area. For example, in radar systems, a mechanical or electronic scanner moves the antenna or sensor beam in azimuth and sometimes elevation to scan the surrounding airspace or terrain. This scanning action allows the radar to detect and track targets, perform surveillance, and collect data on the spatial distribution of objects within its coverage area.
The working principle of a scanner depends on its specific design and application. In radar systems, a mechanical scanner typically uses a rotating antenna or reflector to scan the radar beam in a circular or sector pattern across the sky or earth. This rotation allows the radar to cover a large area and detect targets at different azimuth angles. Electronic scanners, on the other hand, use a phased array or electronically steered antennas to electronically adjust the direction of the radar beam without moving parts. These scanners can quickly change the direction of the beam, allowing agile and precise scanning of the radar’s field of view. In both cases, the function of the scanner is to direct the observation or transmission beam of the sensor to acquire data in different directions, facilitating detection, tracking and surveillance operations in radar systems and other applications detection.
