1. A method for detecting at least one moving object in a predetermined detection zone, the method which comprises:
- providing a speed sensor and specifying a detection zone within an illumination zone of the speed sensor;
measuring a speed signal at least upon an entry of a moving object into the illumination zone;
estimating an entry of the moving object into the detection zone on the basis of a speed of the object and a distance between a boundary of the illumination zone and the detection zone.

Abstract
A method for the detection of at least one moving object in a pre-determined detection zone by way of a speed sensor. The method includes the following steps: determining a detection zone within an illumination region of the speed sensor; detecting a speed signal, particularly a Doppler signal, at least with the entry of a moving object into the illumination region; estimating an entry of the moving object into the detection zone on the basis of a speed of the object, and of a distance between a boundary of the illumination region and the detection zone.

10. A presence detector for detecting at least one moving object in a predetermined detection zone, comprising:
-
a speed sensor for measuring a speed signal at least upon an entry of a moving object into an illumination zone of said speed sensor; a control unit for specifying a detection zone within the illumination zone of said speed sensor; and an evaluation unit connected to said speed sensor for estimating an entry of the moving object into the detection zone based on a speed of the object and a distance between a boundary of the illumination zone and the detection zone. - View Dependent Claims (11, 12, 13, 15)
