Title: Systems for radio direction finding
IPC: G01S1/02
Filed: 1942-01-09
Abstract: 554,251. Wireless direction-finders. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Jan. 9, 1942, No. 383. [Class 40 (v)] In a direction-finder using a continuously rotating aerial or search coil or equivalent arrangement, the beam of a cathode-ray tube is continuously rotated to trace a circle and is deviated radially by potentials applied to the second anode either by the received signal or by a local generator of saw-tooth or sine-wave voltage, the received signal, in the latter case, being applied to the grid of the tube. In the arrangement shown in Figs. 2 and 3, the beam is caused to trace a circle a in any convenient way not shown, and is deflected radially to give the pattern b or c by the second anode 6 when its potential is varied by a valve 2, biased to just below the parabolic part of its characteristic, the grid 3 being connected to the intermediate frequency circuit of the receiver. Alternatively, the valve 2 may be replaced by an amplifier, so that the intermediate frequency is applied to the second anode, Figs. 4 and 5 (not shown). In a third arrangement, Figs. 11 and 12 (not shown), the beam traces a circle off the screen and is deflected radially on to the screen, so that the direction is indicated by two inwardly directed peaks. In a fourth arrangement, Figs. 6 and 7, the circular movement of the beam is converted into a spiral one by applying a saw-tooth voltage from valve L1 to the second anode, the detected signal being applied by a valve L2 to the grid G. The spot remains invisible except when the detected signal is received and illuminates a radial line A giving the desired direction. In Figs. 8 and 9, the circular movement of the beam is converted into a sine curve disposed over an annular area a, Fig. 9, by connecting an alternating current source G to the first and second anodes A1, A2, the detected signal from receiver R being applied to the grid of the tube. The spot is normally extinguished but is illuminated when a certain signal amplitude is received and illuminates a radial line as at b, Fig. 9. In the modification shown, in Fig. 10, signals from valve L are applied as in Figs. 2 and 7 to the second anode of the tube through transformer T<SP>1</SP>, and in addition signals are applied through transformer T<SP>2</SP> to a rectifier D, the load resistance R of which is connected to the grid G of the tube so as to reduce the luminosity for small radial displacements of the spot by reducing the beam density. Specification 530,979 is referred to.
