Volume search radar is a type of radar system specifically designed to scan a large volume of airspace or terrain. Unlike traditional search radars that scan primarily in azimuth and elevation, volume search radars use three-dimensional scanning capabilities, covering a spherical or conical volume around the radar system. This allows them to detect and track targets not only in horizontal and vertical planes, but also at different distances from the radar.
Volume-seeking radars are commonly used in air defense systems, providing comprehensive surveillance and early warning capabilities against airborne threats.
A search radar is a radar system designed to scan a specific area of interest, such as airspace or the Earth’s surface, to detect and track targets. It works by emitting radio waves in a scanning pattern across a wide azimuth and elevation, searching for radar returns reflected from objects within its coverage area.
Search radars are essential in military, maritime and aeronautical applications for surveillance, reconnaissance and early warning purposes. They help identify and monitor targets, provide situational awareness, and support tactical decision-making in defensive and offensive operations.
RMA in radar stands for Range Migration Algorithm. It is a signal processing technique used in synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR) systems to compensate for the range migration effect caused by target movement compared to radar.
During the coherent processing interval, moving targets may shift their positions across range bins, leading to image degradation and blurring in SAR and ISAR images. The RMA algorithm corrects this effect by adjusting the range profiles of moving targets, ensuring precise target positioning and high-resolution imaging in radar applications
