Radar Detectors Owe Their Existence To The Military
If necessity is the mother of invention, than government experiments must be the father. As it is with so many great inventions, radar (and the detectors that have since resulted) owe their entire existence to military necessity.
Radar in its earliest form was created during World War II to help Allied forces track ships, planes and other craft of warfare. Standing for Radio Detection And Ranging, radar was tweaked through the years to become the incredible technology we know today. From law enforcement uses to weather predictions, the military’s radar has been adapted and added to for a variety of practical purposes since it first came on the scene in the 1940s.
Tweaking of radar has resulted in the bane of drivers – the radar guns law enforcement officers use to track their cars. Operating using radio waves, these devices employ the Doppler Shift to clock speeds and present practically airtight cases against drivers in court. Using multiple radio frequencies to track drivers, radars used by law enforcement officers have come a long way from the original form first employed in WW II. Inasmuch, it’s also become a trickier undertaking for drivers to detect the use of radar in the area.
Small, portable and quite effective, radar guns are used by police agencies all over the world. The problem for drivers is the fact the technology has come so far, police have a number of options at their disposal for tracking speeds. With this in mind, detector technology has been forced to advance to read a number of difference frequencies at once just to be considered effective.
As time has moved forward since the 40s, so too has other forms of technology. Law enforcement now not only uses radar, but it has employed laser to track speeds as well.
Motorists who want to level the playing field and be able to watch the watchers must now consider multi-faceted detection devices. In principle though, the technologies of today – both radar and laser – owe their roots to the past.
Joining the ranks of such inventions as kidney dialysis, CAT scans, scratch resistant lenses and more, radar is simply an example in a long line of inventions that were created by government, or for government related purposes, that has resulted in other practical uses.
