Filed: 1962-09-06
Abstract: 1,041,589. Radio distance-measuring. MULLARD Ltd. Sept. 6, 1962, No. 34256/62. Heading H4D. Receiving apparatus for measuring the range of a distant radio transmitter by triangulation and direct phase comparison comprises means for measuring the curvature of the phase front of radio-frequency energy incident upon two mutually-orthogonal aerial arrays by measuring small differences in phase angle of the energy incident upon different aerial elements of each array, and means for computing from said phase angle differences the range of the transmitter. Each of the two mutually-orthogonal arrays may comprise a first pair of spaced aerials and a second pair of spaced aerials all disposed along a single axis, means being provided for measuring in each array the phase angle between signals arriving at the aerials of one pair and the phase angle between signals arriving at the aerials of the other pair. Further means are provided for measuring the difference between the said two phase angles, the range being computed by applying the formula where ## is the difference phase angle for one linear array, ## is the difference phase angle for the other linear array, # is the wavelength of the received signal, d is the distance between the aerials of a pair, D is the distance between the centre of one pair and the centre of the other pair of aerials in a linear array, and R is the range of the transmitter, d being the same for each pair of aerials and D being the. same for each linear array. The formula is derived mathematically with reference to Fig. 1 (not shown) in which one of the arrays is shown diagrammatically. In a modified apparatus utilizing three orthogonal linear arrays with a common centre (Fig. 2, not shown), the computing means applies the formula where ## is the difference phase angle for the third linear array. In each linear array one aerial may be common to the two pairs so that d=D; moreover, the common aerial of one array may serve as the common aerial of another array. The phase-angle information may be extracted from video signals derived from trigonometrical circuits using non-linear elements (Fig. 4, not shown); alternatively (Fig. 6, not shown), the phase angle information may be extracted by frequency-mixing the signals received by different aerial elements in singlesideband modulators and then comparing the resultant frequency-mixed signals to obtain the phase-angle differences.
