what is x-band radar
Best Answer: X-Band. The first frequency band allocated for police radar: 10.5 - 10.55 GHz. Dating from the 1950s, X-band radar is the easiest to detect because of its lower frequency and higher power output. Depending on terrain, temperature and humidity, X-band radar can be detected from a distance of 2 to 4 miles, yet it can only take accurate readings of speed from a distance of 1/2 mile or less.
