## How many feet per microsecond does radar travel?

To relate radar timing to distances traveled by radar energy, you should know that radiated energy from radar set travels at approximately 984 feet per microsecond.

### How is the range of a radar mile determined?

This 12.36-microsecond time interval is sometimes referred to as a RADAR MILE, RADAR NAUTICAL MILE, or NAUTICAL RADAR MILE. The range in kilometers to an object can be found by measuring the elapsed time during a round trip of radar pulse and dividing this quantity by 6.66.

Patrol speed shadowing from moving vehicles can occur when the radar is passing relatively slow moving traffic such as large vehicles, tractor-trailers, and a line of vehicles.

How does moving mode radar measure traffic speed?

Moving mode radar measures the closing or opening traffic speed relative to the radar. Traffic speed is derived from patrol vehicle speed, any error in patrol speed translates directly to a traffic speed error.

## How does police radar work in same lane mode?

Same Lane mode allows the officer to clock same-direction vehicles ahead of the rolling cruiser. If the radar has a rear antenna it can clock faster vehicles as they come up from behind. Fastest Speed mode allows the radar to sample multiple targets and display the speed of the fastest.

### Where to look for police radar on a highway?

If you’re driving on a highway with a center divider, look for radar in a cruiser parked on the side of the highway. A center divider prevents the U-turn necessary for officers to work opposite-lane traffic in moving mode. Instead they’ll park and target vehicles traveling in the same direction. Freeway on-ramps are a favorite location.

Can a radar gun measure the speed of a vehicle?

Yes, moving radar can clock other vehicles speeds while the officer’s vehicle is moving both going in the same direction or even in opposing directions. These radar guns have a second antenna that measures the patrol cars speed while the other antenna tracks the target vehicle.

How is radar used in the military and police?

The military uses radar to track fighter jets in the sky, weathermen use radar to track clouds in the atmosphere, newer cars use radar to alert you if there’s a vehicle in your blind spot, and police officers use radar to measure the speeds of nearby vehicles.
