What is the purpose of using a higher frequency in radar systems?

Utilizing a higher frequency in radar systems significantly enhances the resolution of the radar. Higher frequencies enable the radar to distinguish between closely spaced objects more effectively. This is due to the shorter wavelength associated with higher frequencies, which allows for finer detail in the reflected signals and facilitates better target discrimination. As a result, operators can obtain clearer images and more accurate positional information of multiple targets, which is crucial for applications that require precise surveillance and tracking.

While increased range can be a factor of other design elements in radar systems, higher frequency alone doesn't guarantee it; similarly, power consumption and coverage area are influenced by various parameters of the radar design. This makes improved resolution the most direct and impactful reason for preferring higher frequencies in radar technology.
