Title: Improvements in or relating to cathode ray tube deflection control systems
Inventor: DAWSON LESLIE HOWARD
IPC: G01S7/14
Filed: 1950-06-07
Abstract: 690,827. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 23, 1951 [June 7, 1950], No. 14237/50. Class 40 (vii). A plan-position-indicator display for a radar system performing a limited search in azimuth, i.e. a sector display, is derived by applying to respective perpendicularly arranged deflecting means of a cathode-ray tube, sweep voltages having amplitudes proportional to # and (1 - #2/2) where # measures in radians the angular portion of the scanning aerial from a datum azimuthal direction. Consequently, so long as 6 is not allowed to exceed, for example, Œ 30 degrees, the deflections are closely approximately proportional to sin # and cos 6. A sweep voltage of constant amplitude is supplied from generator 15 to potentiometer 2 and centre-tapped resistor 14 in parallel, the deflecting voltage applied to the X-plates of the cathode-ray tube 1 and having an amplitude proportional to # being taken from between the centre-tap of resistor 14 and the slider 5 of potentiometer 2. The slider 5 is coupled mechanically to the aerial system 8 so that the linear movement of the slider is proportional to the angular movement of the scanning beam. In an alternative embodiment, Fig. 1 (not shown), the mid-point of the sweep generator is earthed, one X-plate being connected to slider 5 and the other to earth, thus dispensing with the need for centre-tapped resistor 14. The deflecting voltage for the Y-plates is taken from between the ends of the resistor 10 and a shortcircuited potentiometer 9, a current of constant amplitude and derived from the generator 15 being passed to earth through the resistor 10 and potentiometer 9. The slider 11 of poten. tiometer 9 is moved linearly in accordance with the angular movement of the aerial 8, the values of the resistors 9 and 10 being so chosen, and the amplitude of the constant current being so fined by means of a large series resistor, that the deflecting potential applied to the Y-plates of the cathode-ray tube 1 varies as (1 - #2/2). The display is described as having particular application to a frequency-modulated radar system.
