What frequency range do police radar signals typically exceed?

Police radar signals typically operate in the frequency range of approximately 10.5 to 36 gigahertz (GHz), which translates to tens of billions of waves per second. The choice indicating ten billion waves per second aligns with the lower portion of the commonly used radar frequencies, specifically in the K-band and Ka-band, which are frequently utilized for speed detection.

Given that police radar systems need to detect the speed of moving vehicles, they require frequencies that can effectively measure Doppler shifts caused by the moving targets. The accuracy and reliability of these signals depend on their wavelength and the specific bands utilized, which often start at around ten billion waves per second. Thus, this frequency not only fits within the operational parameters of radar technology but also highlights the capabilities of law enforcement equipment to function in various conditions while maintaining operational efficiency.
