Title: Radio direction finding receiver equipment
Inventor: EARP CHARLES WILLIAM
IPC: H01Q3/24
Filed: 1963-06-12
Abstract: 1,041,777. Automatic phase control systems; radio navigation. STANDARD TELEPHONES & CABLES Ltd. June 12, 1963, No. 23399/63. Headings H3A and H4D. Relates to a Doppler VOR radio-navigation system as in Specification 1,015,592 in which a central aerial continuously radiates an AM carrier, and upper and lower sideband frequencies are fed alternately and in turn to a ring of surrounding aerials to simulate constant and equal speed rotations (30 c/s.) of two diametrically opposite aerials. Hence, by Doppler effect, two identical FM waves are received at a distant point, the azimuth of this point being determined by the phase of the FM's detected thereat relative to that of a detected reference wave amplitude modulated on to the carrier transmitted from the central aerial. According to the invention phase errors produced in the receiver in the reference A.M. signal are corrected by using a further higher reference frequency signal, also derived from the transmitted signals. The detected AM wave, for example 30 c/s., is filtered at 6 and any phase errors introduced by the filter corrected by phase comparing the filter input and output in a comparator 9 whose output through a motor 10 adjusts a tuned circuit or reactance circuit in the filter to correct the phase. Subsequently the motor 10 is automatically switched to a phase comparator 13 which compares a 150 c/s. harmonic of the filter 6 output with a higher reference detected frequency, for example, 750 c/s. or a 150 c/s. harmonic of it to produce a fine correction of the detected AM signal. The latter is then used as a reference for phase comparison with the incoming detected FM signal at 1, a motor 7 adjusting a phase shifter 4 in the path of the 30 c/s. detected FM wave at 2 until the inputs to the phase detector 3 are in quadrature when the motor stops. The higher detected reference frequency of 750 c/s. is derived by using 25 equi-spaced aerials in the " side-band " ring of aerials, this frequency then being present in the AM signal and derived from the AM detector. Tn a modification Fig. 3 (not shown), a 150 c/s. harmonic of the 30 c/s. frequency modulation is detected by a harmonic-modulation frequency-discriminator, operating by phase comparing the output of a series of eight band pass circuits forming a delay line, with an undelayed input to the phase discriminator. This 150 c/s. output is then phase compared in a fine comparator, Fig. 2 (not shown), with a 150 c/s. harmonic of the reference 30 c/s. phase corrected output of filter 6 (Fig. 1) to produce an error signal switched to actuate the motor 7 for fine control of the phase shifter 4, after coarse control has been effected by phase comparison of the 30 c/s. outputs in question. The motor actuated phase shifter 4 drives through a 5/1 reduction gearing a further fine control phase shifter between the harmonic modulation frequency discriminator and the fine control comparator.
