ABSTRACT:
2. A combination proximity fuze comprising a radio circuit and an infrared ircuit, said radio circuit operative to produce a first voltage impulse when a reflected electromagnetic wave is received from a target, said infrared circuit operative to produce a second voltage impulse when a heat source from a target is detected, a first memory circuit connected to said radio circuit for storing said first voltage impulse for a first predetermined time interval, a second memory circuit connected to said infrared circuit for storing said second voltage impulse for a second predetermined time interval, a coincidence firing circuit connected to said first memory circuit and to said second memory circuit whereby a primer may be ignited when said first and second voltage pulses are applied to said coincidence firing circuit simultaneously within said first and second predetermined time intervals.
