Title: Arrangement for the automatic plotting and instantaneous warning relating to the path of a missile
Inventor: NARBAITS-JAUREGUY JEAN RAYMOND
IPC: G01S3/786
Filed: 1966-07-01
Abstract: 1,220,071. Infra-red position finding. J. R. NARBAITS-JAUREGUY. 1 July, 1966 [9 July, 1965], No. 29773/66. Heading H4D. In a missile path plotting system, infra-red signals emitted by the missile are received at two spaced detectors, the outputs from which are applied to a computer which derives the missile path and either indicates it directly or supervises the firing of an anti-missile device. The arrangement operates in the presence of strong illumination, e.g. sun light. When signals are received from a second, rear missile, plotting operation of the system is stopped for a predetermined interval, so as to prevent the saturation of the receiver memories with coordinates of points which are too near to each other. Processing of the path co-ordinates at the receiver includes the read-out from the storage memories at a slower rate than the detector scanning so as to reduce the band width and thus to facilitate radio transmission. Binary computing is used in conjunction with either electric or negative memories. An optical marking system is caused to follow the target movement by an automatic control in which the signals corresponding to the optical markings are compared with the elevation and bearing signals stored in memories. The optical markings are applied to the detector camera objective through a semi-transparent mirror during suppression of the target image by a shutter.
