Patent Number: 6,169,512

Title: Signal wave based detection system and method, with direction dependent transmission parameter

Abstract: An object detecting apparatus uses a radar system 24 which employes a directional antenna 6. A transmission parameter of the system 24 is calibrated for each transmission direction such that, at a boundary 22 of a detection area 20, there is a maximum signal intensity and a minimum sensitivity. The calibration is effected using reflectors of known reflective response which are positioned around the boundary 22 during calibration.
