G01S0003520000 using a receiving aerial moving, or appearing to move, in a cyclic path to produce a Doppler variation of frequency of the received signal 1
G01S0003540000 the apparent movement of the aerial being produced by coupling the receiver cyclically and sequentially to each of several fixed spaced aerials 1
G01S0003560000 Conical-scan beam systems using signals indicative of the deviation of the direction of reception from the scan axis 1
G01S0003580000 Rotating or oscillating beam systems using continuous analysis of received signal for determining direction in the plane of rotation or oscillation or for determining deviation from a predetermined direction in such a plane (G01S0003160000 takes precedence);; 1
G01S0003600000 Broad-beam systems producing in the receiver a substantially-sinusoidal envelope signal of the carrier wave of the beam, the phase angle of which is dependent upon the angle between the direction of the transmitter from the receiver and a reference direction from the receiver, e.g. cardioid system 1
G01S0003620000 wherein the phase angle of the signal is indicated by a cathode-ray tube 1
G01S0003640000 wherein the phase angle of the signal is determined by phase comparison with a reference alternating signal varying in synchronism with the directivity variation 1
G01S0003660000 Narrow-beam systems producing in the receiver a pulse-type envelope signal of the carrier wave of the beam, the timing of which is dependent upon the angle between the direction of the transmitter from the receiver and a reference direction from the receiver; Overlapping broad-beam systems defining in the receiver a narrow zone and producing a pulse-type envelope signal of the carrier wave of the beam, the timing of which is dependent upon the angle between the direction of the transmitter from the receiver and a reference direction from the receiver 1
G01S0003680000 wherein the timing of the pulse-type envelope signal is indicated by cathode-ray tube 1
G01S0003700000 wherein the timing of the pulse-type envelope signal is determined by bringing a locally-generated pulse-type signal into coincidence or other predetermined time-relationship with the envelope signal 1
G01S0003720000 Diversity systems specially adapted for direction-finding 1
G01S0003740000 Multi-channel systems specially adapted for direction-finding, i.e. having a single aerial system capable of giving simultaneous indications of the directions of different signals (systems in which the directions of different signals are determined sequentially and displayed simultaneously G01S0003040000, G01S0003140000) 1
G01S0003780000 using electromagnetic waves other than radio waves 1
