This cache is placed on the Industrial estate and is NOT on the airfield.
It is in view of the airfield radar scanners at Hawarden Airfield. Access to the GZ is off Manor Lane via Manor Road.
Please be aware of muggles as the area is popular with dog walkers and is frequently used by HGV drivers as overnight parking.
RADAR is an acronym of the phrase RAdio Detection And Ranging. Originally called RDF (Radio Direction Finding) it was developed during the 2nd world war as a means of detecting German bombers. A series of Radar stations along the south coast of England, called the “Home Chain”, gave warning of the approaching enemy bombers. RAF fighters were then scrambled to identify and intercept the threat.
In its simplest form, radar works by sending out a pulse of high frequency radio energy and measuring the time taken for a return signal from the target in a similar manner to that of an echo across a valley. This was all made possible by the invention of a device called a Magnetron. Today the magnetron resides in nearly every kitchen around the world as it is the main component in every microwave oven.
Modern radars and now very sophisticated and can measure not only range but height, bearing and speed of targets. They are used to guide aircraft and ships and modern military fire control radars can deliver ordnance with pinpoint accuracy.
