Abstract:
In radio direction finding it is common to assume that the radio wave\'s front is planar. Sphericity of radio wave allows radio source\'s location measurement by single-point phase direction finder. This direction finder\'s antenna system includes two orthogonal linear three-element antennas with one common antenna in the center. Analytical model of radio emission source\'s location finding is discussed. Proposed block diagram of the devise is shown. Boundaries are determined when neglection of radio wave\'s curvature is impossible. Offered approach allows jammers location finding by their azimuth and distance measurement.
