Abstract:

The patent describes apparatus for instantaneously determining whether the angle of arrival of a signal is within an antenna main lobe or within a side lobe. The apparatus uses a high gain, highly directive antenna and a low gain, broad pattern antenna, in combination with a local oscillator, limiting amplifiers and a phase sensitive detector. The antennae are mounted so that their centers of radiation are coaxial and on a plane perpendicular to the axes of their respective main receiving lobes.
