1. A microwave signal detector comprising a microwave sensitive receiving means, said microwave sensitive receiving means including a microwave responsive element comprising a horn element forming a microwave cavity and having a microwave-responsive diode mounted in said cavity and serially connected to a resistive voltage divider network, said microwave responsive element being responsive to microwave energy signals generated from a remote source to produce a noise signal at an audio frequency resulting from vibration of the responsive element, means connected to said microwave responsive element for coupling said noise signal produced in response to received microwave energy, a comparator for comparing the noise signals to a predetermined threshold voltage, and indicator means for providing an indication of the detection of a source of microwave energy when the value of the developed noise signal exceeds the threshold voltage.
