  • Circuitry for determining direction of impingement of a received signal
    Patent number: 3935575
    Abstract: An improved system for determining the direction of impingement of a received energy signal, of the type having a plurality of receivers forming pairs of mutually perpendicular dipoles for receiving the orthogonal components of the impinging signal, apparatus for measuring these received components in order to produce signals indicative of the direction of impingement, and a display device connected to the output of the measuring apparatus. The measuring apparatus is provided with a plurality of amplifier circuits each of which is connected to a respective one of the receivers for producing a constant amplitude representation of its received signal. The use of these amplifiers helps to eliminate errors that would otherwise occur in the measurements due to inaccuracies in the measured amplitudes of the received dipole signals.
