Moving object detecting device

摘要

A moving object detecting device is arranged for detection in time series of an angle of respective received-wave signals at every moment with respect to basic axes in a vector plane, the basic axes being a pair of intermediate signals obtained by converting frequency deviation components of the received-wave signals responsive to incident on a wave receiver of reflected waves of radiated energy by a wave radiator from an object moving in a supervisory zone. Such moving object can be thereby detected at a high precision, irrespective of how quickly or slowly it moves within the zone.
