What are the three basic types of Search RADAR?

• A. Surface-Search, Air-Search, Height-Finding
• B. Ground-Search, Air-Search, Height-Finding
• C. Surface-Search, Air-Search, Long-Range
• D. Surface-Search, Near-Search, Height-Finding

Answer: (A)

Radar search types are defined by what they detect and the kind of information they provide. The standard trio focuses on three functions: surface targets, air targets, and height information. Surface-Search radar is used to locate ships and other objects on the water’s surface, giving bearing and range to surface contacts. Air-Search radar is tuned to detect aircraft, again providing bearing and range to aerial targets and serving as the main early-warning and target-acquisition tool. Height-Finding radar is a specialized type that determines how high a detected target is, typically by vertical scanning or multiple-angle measurements, to add the third dimension to tracking. This combination—surface, air, and height—covers locating targets on the surface, detecting aerial targets, and measuring altitude, which is why it is the standard set for Search RADAR. The other terms listed aren’t established categories of radar search types, since they either describe capabilities rather than distinct radar types or use terms not used in standard classifications.
