Transmitter and receiver devices are included in an active optic proximity fuse for providing increased resistance to aerosols. The transmitter and receiver units operate with optical radiation and include a signal processing unit which reacts to a target located in a sensing region and reflecting optical radiation emitted from the transmitter device to the receiver device. The sensing region displays, most proximal a carrier of the proximity fuse, an inner sensing limit which is located at an inner distance from the carrier. The signal processing unit operates with preparatory signal processing and/or time measurement of reflected signals when the target is located within the sensing region, and emits an activation signal only when the target passes the inner sensing limit.

In an active optic proximity fuse, an apparatus for providing increased resistance to precipitation, smoke, and clouds, comprising: a transmitter device for emitting optical radiation; a receiver device for receiving said optical radiation which has been reflected by a target located within a sensing region of the proximity fuse; a signal processing unit connected to the output of said receiver device, said signal processing unit including: (a) a threshold device for receiving said output signal from said receiver device and for generating an output signal when said received signal exceeds a predetermined threshold level of said threshold device; and (b) at least one rear edge triggered flip-flop device connected to the output of said threshold device for receiving an output signal from said threshold device and for emitting a triggering signal which is controlled by a rear edge of said output signal from said threshold device.
