Summary
[edit]DescriptionRadar speed gun internal works.jpg |
English: Inside a disassembled radar speed gun, used by police to measure the speed of cars. The copper-colored cone is the horn antenna which emits the beam of microwaves. The small grey unit mounted at its apex is a 24GHz Gunn diode oscillator which generates the microwaves. The GaAs Gunn diode is mounted inside a resonant waveguide cavity diecast from Mazak zinc aluminium alloy. |
