Which type of radar operates on a frequency of 24 GHz?

The correct answer is based on the classification of radar frequency bands. K-band radar operates specifically within the frequency range of 24 GHz, which is recognized for its effectiveness in measuring speed and distance. This frequency is commonly utilized in law enforcement for traffic radar, as it offers a balance between range and resolution.

In contrast, other bands do not operate at this frequency. X-band radar typically operates between 8 to 12 GHz, which is lower than the K-band. Ka-band radar, while it also encompasses some high-frequency applications, operates typically between 26.5 to 40 GHz, which is above the specified 24 GHz. C-band radar operates between 4 to 8 GHz, which places it significantly below the K-band range. Understanding these distinctions is crucial for radar operation and application, particularly in contexts such as law enforcement, where radar frequency plays a role in performance and detection capabilities.
