ABSTRACT: RADIO DIRECTION-FINDING A radio direction-finding system comprises at least two adjacent, coplanar rectilinear antenna arrays (ARR1, ARR2) which face in different directions; phase measurements are performed on pairs of antennae of different spacings (ANTC/ANT1-ANTN) in each array in order to derive the direction of incidence in the plane of the arrays and/or the direction of incidence with respect to said plane, e.g. bearing (?) and elevation (.beta.) respectively. To reduce the number of channels required for resolving ambiguity in the phase measurement on the widest-spaced antenna pair (ANTC/ANTN) in each array, ambiguity is resolved as far as possible with more closely spaced pairs in each array and finally resolved on the two arrays jointly by amplitude comparison of signals received by the two arrays, even though the accuracy of the amplitude comparison may be insufficient to resolve ambiguity in the arrays separately. The invention is particularly applicable to a broadband system for radio sources which may be at substantial angles of elevation, e.g. up to 50 degrees.
