Abstract
A proximity fuse for a launchable unit, for example a missile, includes transmitters for emitting optic radiation in a plurality of narrow part lobes, and receivers for receiving optic radiation emitted through the part lobes and reflected from a target towards which the unit is homing in. The receivers are enabled to discern reflecting radiation derived from each respective part lobe from the radiation emitted and reflected from other part lobes. The radiation derived from each respective part lobe is processed individually in the receiver.
Claims53
A proximity fuse for a unit in the form of a missile, projectile or the like and comprising transmitter means for emitting electromagnetic radiation in a plurality of part lobes, receiver means for receiving the radiation which is reflected from a proximally adjacent target, and signal processing means for processing an electric signal initiated by the received radiation, wherein said transmitter and receiver means are operative to work with a plurality of narrow part lobes distributed in dense configuration about the circumference of the unit, each of said narrow part lobes respectively impinging in their entirety upon the target;
- and wherein said receiver means are operative to discern the reflected and received radiation of each respective part of lobe for individual processing in said signal processing means.
An optical receiver intended for a unit in the form of a missile, projectile, or the like, for receiving two or more reflected optical strobes of different angles of incidence towards the unit, wherein the receiver includes two pairwise cooperable receiver units which are each allocated their strobe or group of strobes;
- that the two receiver units are connected to an electric signal initiation circuit, which, in response to reception, by the receivers, of each respective strobe, generates electric signals representative of each respective receiver unit;
- and that means sensing said signals indicate that one of said receiver units which is actuated, on the occasion in question, by the relevant strobe.
An optical receiver intended for a unit in the form of a missile, projectile, etc., for receiving two or more reflected optical strobes of different angles of incidence towards the unit, wherein the receiver includes two pairwise cooperable receiver units which are each allocated their strobe or group of strobes;
- that the two receiver units are connected to an electric signal initiation circuit by means of photodetection means, which, in response to reception, by the receivers, of each respective strobe, generates electric signals representative of each respective receiver unit;
- and that means sensing said signals indicate that one of said receiver units which is actuated, on the occasion in question, by the relevant strobe, the photodetection means included in said receiver units being interconnected in the signal initiation circuit such that the signals initiated by intermediary of each respective receiver unit occur with different signs.
