Abstract

971,466. Pulse radar. SOC. NOUVELLE D'ELECTRONIQUE ET DE LA RADIOINDUSTRIE. Feb. 14, 1961 [Feb. 19, 1960], No. 5483/61. Drawings to Specification. Heading H4D. In the automatic digital processing of data representing the co-ordinates of an object, measured plane co-ordinates A of the object are compared with predetermined co-ordinates B defining an area, such that if co-ordinates A fall within that area a third co-ordinate is added to co-ordinates B, and the arrangement includes different stores for co-ordinates A and B, digital computing circuits, and continuous measurement of co-ordinates A. The invention is particularly described as applied to a scanning- beam pulse radar providing spherical polar coordinates A from which (1) a device D derives spherical polar co-ordinates A<SP>1</SP> representing the centre of a target, (2) a co-ordinate converter provides three-dimensional Cartesian co-ordinates A<SP>11</SP>, the X, Y components of which are released by a pulse from device D to feed a comparator also fed with programmed plane Cartesian co-ordinates X 1 , Y 1 defining a " window " X 1 Œ#X 1 , Y 1 Œ#Y 1 ; if the X, Y components of co-ordinates A fall within the window the Z component (height of target) is added to X 1 , Y 1 and (X 1 , Y 1 , Z) is fed to a utilization means. The stores comprise magnetic core matrices. Programmed machine tool control is mentioned.
