Determining the “best” ground surveillance radar depends on the specific operational requirements and intended application. Ground surveillance radars are designed for a variety of purposes, including military surveillance, border security, and perimeter surveillance. Factors that contribute to the effectiveness of a ground surveillance radar include its range, resolution, detection capabilities (including weak radar cutting targets), mobility and integration with other systems sensors.
Some widely recognized ground surveillance radar systems include the Thales Master series, Lockheed Martin TPS-77, and the ELM-2084 series by Elta Systems. Choosing the best ground surveillance radar often depends on factors such as the operational environment, terrain, and mission objectives.
The most powerful radar system currently in operation is debatable, as it depends on the criteria used for measurement, whether by power, range or capacity.
However, one of the most historically powerful radar systems was the Duga radar system (nicknamed the “Russian woodpecker”), developed by the Soviet Union during the Cold War era. This over-the-horizon (OTH) radar system was used for early warning and detection of ballistic missile launches.
Modern examples of powerful radar systems include phased array radars used in missile defense systems, such as the AN/TPY-2 radar associated with the Terminal High Area Defense (THAAD) system deployed by the United States.
Radar systems designed for ground targets, commonly called moving target indicator (GMTI) radars, are specialized for detecting and tracking moving objects on the ground. These radars are essential for military reconnaissance, surveillance and intelligence gathering missions.
GMTI radars use advanced signal processing techniques to differentiate moving targets (such as vehicles or personnel) from stationary clutter (such as buildings or terrain features). They provide real-time tracking and situational awareness, enabling military forces to monitor ground activities, detect threats and support tactical decision-making. Examples of GMTI radar systems include SAR/GMTI radars used on surveillance aircraft and ground-based radars like the Raytheon Enhanced Pathfinder Radar (EPR) system
