    As Jedi said, no. The only way radio and microwaves can harm you is by transferring enough energy over a short enough period of time to burn you. This requires very high power outputs, much higher than the radar in a car puts out. For example, a car radar requires about 10 milliwatts of power to detect a man-sized object at 200 meters.

  4. Wraith ARS 2X After months in development and a ridiculous amount of testing, I present to you my second radar resource for FiveM, the Wraith ARS 2X. It is a full rewrite of WraithRS, with a completely custom system for detecting vehicles in the radar’s line of sight, allowing vehicles to be...

  5. Got some new old wheels for a midlife crisis. Set up for the corners. 1996 wrx sti type ra v-limited Its a re-body so unfortunately exterior colour is not correct. Freshly finished build. Interior is what is is. Aged. But not too shabby imo. Only task to finish is the exterior panel and...

  6. A positive effect of curved plastic would be the condenser lens in front of most Radar and Radar Receiver antennas. Most antennas in use today are not full wavelength antennas, but rather shortened antennas with sharply tapered horns. This abbreviated horn design causes the wave front to bulge as it passes down into the horn (not a good thing).

  7. Escort’s Drive Smarter app recent received an update that adds support for Apple CarPlay. With this latest update, you can now use your vehicle’s display for not only turn-by-turn navigation, but also to display your radar detector’s radar and laser alerts, cloud alerts shared with other...

  8. How does a radar gun determine velocity? - Physics Forums

    www.physicsforums.com/threads/how-does-a-radar-gun-determine-velocity.578365

    A radar gun measures velocity by sending out a radio wave towards a moving object, such as a car. The radio wave bounces off the object and returns to the radar gun. By measuring the time it takes for the wave to return, the radar gun can calculate the velocity of the object based on the known speed of the radio wave.

  9. Packing up a radar detector for air travel for use in a rental car is a frequent occurrence for detector enthusiasts. Many detectors utilize a "super sticky" suction cup, which can easily get dirty while sitting in your luggage as it picks up dust particles from other items such as clothing.

  10. Calculating Speed with a Radar Gun: Exploring Doppler Shifts

    www.physicsforums.com/threads/calculating-speed-with-a-radar-gun-exploring...

    the wave emitted from a stationary radar gun to a moving car does experience two Doppler shifts. 1. when the source (radar gun) is stationary and the observer (car) is moving. 'A doppler effect also occurs when an observer moves towards a source, but here the wavelength does not change, instead it is the effective velocity that changes and ...

  11. Michael Valentine of Valentine Research passes away at the age of 74. Mike's vision and innovation at Valentine Research and Cincinnati Microwave forever transformed the radar detector industry. His relentless pursuit of excellence led to advancements that empowered countless drivers, making him a true pioneer in the field.
