Abstract
The invention relates to a method for increasing the accuracy of a measurement of a radio-based locating system comprising a mobile station and at least one fixed station, wherein the movement of a mobile station from an initial position is detected by way of measuring data of an absolute sensor system and a relative sensor system, a virtual antenna is embodied in the form of synthetic aperture by way of measuring data and the mobile station is focused on the fixed station and/or vice versa by using the synthetic aperture.

1-20. (canceled)
A method for increasing measurement precision of a radio-based positioning system comprising a mobile station and at least one stationary station, the method comprising:
- detecting a movement of the mobile station starting from an initial position, the detecting utilizing measurement data of an absolute sensor system and a relative sensor system;
- generating a virtual antenna in a form of a synthetic aperture utilizing the measurement data, and
- focusing either:
- a) the mobile station on the stationary station and;
- b) the stationary station on the mobile station, the focusing utilizing the synthetic aperture.
A device to increase measurement precision of a radio-based positioning system, comprising:
- a mobile station;
- at least one stationary station;
- an absolute sensor system generated from at least one secondary radar and at least one transponder;
- at least one relative sensor system provided for quantification of a magnitude and a direction of a position change of the mobile station relative to an original position;
- a signal processing device for common processing of measurement data acquired via the absolute sensor system and the relative sensor system for generation of a virtual antenna in a form of a synthetic aperture;
- and
- a focusing device for successive focusing of at least one of:
- a) the mobile station on the stationary station and b) the stationary system on the mobile station on based on the synthetic aperture.
