In which scenario is a 3-cm radar most advantageous?

A 3-cm radar operates in the microwave frequency range, enabling it to achieve high resolution and sensitivity, particularly effective for tracking aerial targets. This wavelength is beneficial for detecting fast-moving objects like aircraft due to its ability to provide detailed information about their position and velocity. The shorter wavelength of 3-cm radar allows it to detect smaller targets and obtain better resolution in range and bearing, which is crucial for accurately tracking aerial objects.

In scenarios involving aerial targets, the rapid changes in altitude and direction require a radar system that can respond swiftly and provide precise tracking information. A 3-cm radar is tailored for the quick detection and tracking of these types of targets, making it particularly advantageous in air traffic control and military applications where aerial surveillance is key.

The other scenarios involve different challenges where a 3-cm radar may not be as effective. For instance, shallow waters with strong currents might benefit from radar systems with different wavelengths more suited for detecting surface vessels. Extended range over the horizon generally requires longer wavelengths that can propagate better over vast distances. Adverse weather conditions like heavy rain or fog can severely attenuate higher frequency radar signals, leading to diminished performance and reliability. Therefore, the use of 3-cm radar is best suited for
