What Band Do Police Radars Use

What band do police radars use? We've unlocked the answer.

In this detailed guide, we'll explore the intricacies of X, K, and Ka bands, the different types of frequencies used by police radars, and how our radar detectors can help you navigate these signals. We'll also take a dive into the functionality of radar detectors.

Our discussion will cover the essentials of what each band represents and how our products, designed with precision and expertise, stand as your best defense against unexpected surprises on the road.

Let's begin.

What this article covers:

What Are X, K, and Ka Band?

Let's briefly discuss how does police radar work. Based on our observations, they use various radio wave frequencies to monitor speed. Knowing the differences between X, K, and Ka bands is essential for optimizing your radar detector's performance.

Here are the specifics.

What Is X Band?

Our findings show that X Band is one of the oldest radar frequencies used for speed detection, operating in the 8 to 12 GHz frequency range. While it's less common today, some traffic radars still use this frequency, especially in certain areas or countries.

It's known for its large wavelength, which means it can be detected from a distance, providing early warnings to drivers. However, because of its older technology, it can also lead to more false alerts from non-police sources.

Radar detectors that can pick up X Band signals are still relevant. Being aware of X Band radars allows drivers to adjust their speed, avoiding potential speed tickets.

What Is K Band?

K Band is a more commonly used frequency range for police radar, operating between 18 to 27 GHz. It's a staple in modern traffic speed monitoring because of its effective balance between range and accuracy.

K Band radars can offer more precise detections than X Band but are also more prone to false alarms from other sources like adaptive cruise control systems in modern cars.

Modern radar detectors are equipped with technology to filter out these irrelevant signals, improving the accuracy of real threat detection.

High-quality radar detectors, like those offered by Escort, combine sophisticated filtering with real-time data to minimize false alarms while maintaining high sensitivity to real police radars.

What Is Ka Band?

Ka Band represents the most recent and widely used frequency range in police radar technology, operating between 33.4 to 36.0 GHz. This band is favored by law enforcement for its shorter wavelengths, which allow for more accurate speed measurement and reduced visibility to radar detectors.

Ka Band radars are highly effective for speed enforcement but also require sophisticated detection equipment to identify them accurately.

Ka Band's dominance in speed enforcement has made it a primary focus for radar detector manufacturers like ourselves. Advanced models are equipped with detailed segmentation options and enhanced filtering capabilities to accurately identify Ka Band signals amidst a sea of other frequencies.
