<p>An object detecting apparatus uses a radar system (24) which employs 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.</p> |
