Title: Improvements in or relating to self-orienting directional radio receivers
Inventor: MARK JOHN RICHARD
IPC: G01S3/32
Filed: 1964-06-26
Abstract: 1,107,378. Aerials. MARCONI CO. Ltd. 11 May, 1965 [26 June, 1964], No. 26517/64. Heading H4A. A tracking receiver comprises an orientable directional aerial system having at least one pair of adjacent aerial elements which receive radio waves both directly and via a reflector means which rotates their plane of polarization by 90 degrees. The directly received signals are used to effect tracking, and the others are extracted as wideband communication signals. As described, a twin horn unit A1, A2, Fig. 1, projects through a main paraboloidal twist reflector B towards a subsidiary planar reflector C made of horizontally disposed parallel wires or strips through which incoming vertically polarized radio waves can pass. One part of the said incoming waves enters the horns A1, A2 directly and reaches two output ports A6, A7 whilst another part is reflected back by the twist reflector B with horizontal polarization towards the reflector C, from which it is reflected and also enters the horns A1,A2, reaching an output port A8 via a branch coupled guide A3, A4, A5. The signals from the ports A6, A7 are fed to a network 1, Fig. 2, which produces separate " sum " and " difference " outputs, which are each subjected to narrow band amplification and fed to a phase and amplitude discriminator 10 after shifting the phase of one 90 degrees relative to the other. The output of the discriminator is fed to an aerial system control unit 12 which controls a motor-driven mechanical drive 13 to the aerial system to cause it to track the source of the signals. The output from the port A8 is amplified in a wide-band channel and is fed to a communication signal utilization means 18. A group of four horns may be provided in which two horns side by side would feed equipment as described above and produce tracking in azimuth and in which two horns placed one above the other would feed similar equipment and produce tracking in elevation.
