Short range passive electromagnetic detector |
摘要 |
A short range passive detector for detonating a mine comprising a bridge circuit which utilizes the mine tripwire wire-to-ground capacitance as one arm of the bridge and associated circuitry for zero adjusting the bridge automatically to render the bridge independent of wire-to-ground height and yet allow sudden changes of capacitance to cause mine detonation.
