| 摘要 |
A passive, infrared, guided missile fuze, capable of detecting the presence of a target, having an axis which coincides substantially with the direction of forward motion of the missile, comprising three infrared detectors for detecting three separate beams of infrared electromagnetic radiation from the target, the beams forming angles with the axis. More specifically, the missile fuze detects the presence of a target when two of the infrared detectors simultaneously detect two beams of infrared radiation from the target. In a sophisticated embodiment, the fuze is able to determine in which quadrant of space the target is located.
