How Radar Works

How Radar Works  By Curtis Sluder  Basically, radar works by sending out a series of radio waves at a specific frequency then calculating the change in frequency when the waves return. Think of the waves as “wiggling” at a certain speed.  When these waves hit things, they bounce off and are scattered in different directions.  Some of the radio waves that hit an object are reflected back to the device that sent out the radio waves. These waves are the ones the radar unit is looking for.  The waves reflected back will “wiggle” at a slightly different frequency, and the computer processor in the radar device can then determine how fast an object is travelling based on how much faster or slower the “wiggle”, or frequency.  These calculations are possible because of the Doppler Effect.  The Doppler effect is the change in frequency of radio waves when an object emitting radio waves is moving (or the item they are reflected off is moving.) As the waves are reflected back, the frequency is higher coming from objects getting closer, and lower when bounced back from objects getting further away.  Think of the change in pitch when a fire truck approaches and passes.  The pitch is high as it approaches, accurate when it is beside you, and lower when it passes and moves away.  The reason is, on approach, each sound wave reaches the hearer slightly faster than the last, because the vehicle transmitting the sound is getting closer.  As it moves away, each sound wave reaches the hearer slightly slower, because the transmitting vehicle is getting further away with each wave. Think of the waves as being pressed together when the siren approaches, and spread apart after it passes....

New Laws Open more possibilities for expunction and cleaning your record

After court is over, and you have either had your case dismissed, been found not guilty, or found guilty and you have taken your lumps. It is over, right? Not so fast. Even if your charge has been dismissed, your criminal record still shows that you were charged with a crime. If you were found or pled guilty, the mark on your record is even greater. And who sees this? Potential employers. College applications. Those entering the military. Obtaining a professional license, leasing a residence, possessing a gun for home defense, all can be stopped short because of a smudge on your record. Even travelling out of the country can be much more difficult due to marks on your record. Even Canada! Recent changes in NC Law may make it possible to clean your record, once and for all! Governor Roy Cooper signed a bi-partisan bill that went into effect December 1, 2017, which may make it possible to have convictions, diversions, and unlimited dismissals EXPUNGED! If you have a misdemeanor conviction more than 5 years old, or *some* non-violent Felony convictions, (level H and I) more than 10 years old, Dismissals, no matter how old, Deferred prosecution, 90-96 Drug Diversion, Convictions before age 18, and some other charges, You may be eligible for an expunction.
