What does Ka band mean on my radar detector?

These false alarms come from moving vehicles with advanced safety systems . Some examples of these systems include auto-pilot, radar cruise control, adaptive cruise control and blind spot monitoring systems. These systems emit K band radar signals which will confuse the radar detector.

Ka band radar are radar waves between 33 . 4 GHz and 36.0 GHz . These are the most recent and the best radar band frequencies that law enforcement can operate on. There are as many as five different frequencies that these waves can operate on.

A short K-band signal that quickly disappears could well be from Blind Spot Monitoring radar in a passing vehicle . If it’s a Ka-band alert, most likely it’s instant-on radar working traffic up ahead. With the radar on hold, the officer triggers it at close range and gets a speed almost instantly.
