What is radar frequency range?

X band radar is a type of radar wave that falls between 8.0 GHz and 12 GHz , with law enforcement radar guns operating around 10.5 GHz. X band is the oldest type of police radar frequency, but it is not used as frequently today as it used to be.

Most radars, in practice, operate between 400 MHz to 36 GHz ; however, there are some notable exceptions. The optical and radio portions of the electromagnetic spectrum occupy positions coincidental with two important transparent bands in the Earth’s atmosphere and ionosphere.

Microwave radars, also called X-band radars, which are limited by line-of-sight propagation to the horizon. Due to the large available bandwidth in the microwave frequency range, the spatial resolution can be as fine as 5 m at 5 km working range .
