20120182174 | Optimizing Switching Sequence In The Case Of Switched Antenna Arrays - An antenna array for a radar sensor, wherein the antenna array has a number of antenna elements linearly arranged next to one another. The antenna elements are designed for transmitting or receiving a radar signal, and the antenna array has a switching unit, which is designed to connect the antenna elements according to a predetermined switching sequence individually, one after the other in time, with a transmitting or receiving unit of the radar sensor. The switching sequence, according to which the antenna elements are connected one after the other with the transmitting or receiving unit, deviates from the spatial sequence of the antenna elements in the antenna array. | 2012-07-19 |

20120182179 | METHOD FOR THE COMPUTER-SUPPORTED CREATION AND/OR UPDATING OF A REFERENCE MAP FOR A SATELLITE-SUPPORTED POSITIONING OF AN OBJECT - Distance dimensions in a predetermined spatial region of a reference map are corrected during positioning of an object from which dimensions the object position is determined from a satellite signal, received via a receiving unit at the location of the object, representing the distance from the satellite to the object. The distance dimensions are determined form received satellite signals using a satellite-supported receiver unit in a plurality of locations of an object in the predetermined spatial region. Using a predetermined object position, which can be known in advance or estimated, distance dimension which corresponds to the predetermined object position are back-calculated by incorporating the satellite positions of the satellites from which the satellite signals are received. Based on the difference between the respectively determined and back-calculated distance dimensions, a correction for at least part of the predetermined spatial region around the specified object position is stored and/or updated. | 2012-07-19 |
