| 20080291078 | Radar System for Motor Vehicles - A radar system for motor vehicles, having a radar sensor and an evaluation device for measuring distances and relative velocities of objects in the surrounding field of the vehicle, and a collision detection device, which, on the basis of the measured distances and relative velocities, recognizes an imminent collision and delivers data on the expected time of collision and the impact velocity to a precrash system. The radar sensor is switchable by the collision detection device to a velocity measurement mode in which a more precise measurement of the relative velocity is made. | 11-27-2008 |
| 20090201193 | Radar sensor and method for analyzing objects - A method and a radar sensor for transmitting frequency-modulated transmitted signals and receiving partial waves reflected by objects in the sensor detection range. A frequency shift of the received signal relative to the transmitted signal is determined for each object reflecting in each frequency ramp, it being possible to determine the relative speeds and the distances of the detected objects from the combination of frequency shifts of a plurality of ramps. The objects detected in preceding measurement cycles are stored in a memory, their relative speed and their distance being computed in advance for a future measurement cycle. The expected frequency shifts are determined and the frequency shifts of a plurality of ramps are combined in order to determine the relative speeds and the distances for objects that have not yet been stored in the memory. | 08-13-2009 |
| 20090303108 | Angular Resolution Radar Sensor - A radar sensor having multiple antenna elements for transmitting and receiving radar signals, an associated transmitting and receiving element and an evaluation device for determining the azimuth angle of located objects on the basis of a relationship between the signals received from different antenna elements, wherein the transmitting and receiving element is designed to supply to the antenna elements transmission signals in parallel, the frequencies of which are offset with respect to one another, and the evaluation device is designed to distinguish between signals that were transmitted by different antenna elements on the basis of the frequency offset. | 12-10-2009 |
| 20100097200 | Method and device for identifying and classifying objects - A method and device for identifying and classifying objects, electromagnetic radiation being emitted by a sensor, the radiation components reflected on objects being received by the sensor, the received signals being analyzed by comparison with stored characteristic values and the class of the reflecting object being deduced on the basis of the analysis. To this end, an analyzer is provided for analyzing the received signals, a memory is provided for storing characteristic patterns, its stored patterns being compared with the analyzed signals and thus the class of the reflecting objects being deducible on the basis of the comparison. | 04-22-2010 |
| 20100231436 | RADAR SENSOR FOR MOTOR VEHICLES - Radar sensor for motor vehicles, having a transmitting and receiving device for microwaves, in which beam-shaping devices which are independent of one another are provided for the azimuth and the elevation, and the beam-shaping device for the elevation has a cylindrical lens. | 09-16-2010 |
| 20100277361 | MOTOR VEHICLE FMCW RADAR HAVING LINEAR FREQUENCY RAMPS OF DIFFERENT SLOPES THAT ARE SET APART, WHICH ARE ASSOCIATED WITH DIFFERENT ANGULAR RANGES - An FMCW radar locating device includes a transmitting device having a controllable transmitting-signal-generating device generating a transmitting signal having a frequency corresponding to an input control signal; a control device connected to the transmitting-signal-generating device and generating the input control signal which controls the transmitting signal such that it rises periodically in a discontinuous, inconsistent linear fashion in first frequency segments, and drops periodically in a discontinuous, inconsistent linear fashion in second frequency segments; and a receiving device for receiving an echo signal reflected by an object and locating an object based on the received echo signal. | 11-04-2010 |
| 20110018784 | ANTENNA, IN PARTICULAR FOR RADAR SIGNALS, AS WELL AS METHOD AND USE - In an antenna, e.g., for radar signals, a substrate carries two pairs of diametrically opposed antenna elements, first diametrically opposed antenna elements being oriented in a direction that considerably deviates from the direction of second diametrically opposed antenna elements, e.g., by 90°, and the first and second diametrically opposed antenna elements each lying symmetrically with respect to the point of intersection of their orientation directions. | 01-27-2011 |
| 20110156973 | ANTENNA - An antenna has an antenna body having a plurality of first antenna elements situated along a first straight line. The antenna body includes a first conductive grounded surface and a second conductive grounded surface, the first and second grounded surfaces being situated essentially parallel to one another. A dielectric is situated between the first and second grounded surfaces. A signal conductor is also situated between the first and second grounded surfaces. The first antenna elements are designed as apertures situated above the signal conductor in the first grounded surface. Furthermore, the antenna is designed to emit a signal in a direction in space, depending on a frequency of the signal. At least two of the first antenna elements differ from one another in such a way that their power emissions are different. | 06-30-2011 |
