Abstract: A method for a radar sensor for a motor vehicle, for angle estimation of radar targets based on an antenna diagram that indicates, for various configurations of radar targets, pertinent amplitudes and/or phase correlations between signals which are obtained for the relevant configuration in multiple evaluation channels of the radar sensor, wherein for a single real target, the occurrence of a number n of apparent targets, which are caused by reflection of the signal coming from the real target from elongated objects, is modeled mathematically; a correlation between the location angle of the real target and the location angles of the apparent targets is calculated; and to estimate the location angle of the real target, a multi-target estimate is performed in an n-dimensional search space and the search is limited to a sub-space that is determined by the calculated correlation.

Abstract: A method is provided for detecting at least two objects, particularly using a radar system having the steps of sending out a first radio signal using a first sending device, the first sending device being situated in a horizontal plane having at least two first antenna elements, receiving the radio signal using the at least two first antenna elements, receiving the radio signal using at least two second antenna elements, which are situated in different horizontal positions each above or below corresponding first antenna elements of the horizontally situated antenna elements, calculating respectively one azimuth angle and one angle of elevation from at least two objects located in front of the first antenna elements and the second antenna elements from the first radio signal received by the first antenna elements and from the first radio signal received by the second antenna elements. Furthermore, an antenna array, a radar system, and a vehicle are provided.

Abstract: In a method for operating a MIMO radar, an influence of an object motion on an angle estimate is substantially eliminated, and a time multiplex schema having a transmission sequence and transmission instants of transmitters of the MIMO radar is identified by optimizing the following mathematical relationship: d _ pulses , opt = arg ? ? max d _ pulses ? [ Var S ? ( d _ pulses ) - ( Cov S ? ( d _ pulses , t ) ) 2 / Var S ? ( t _ ) ] in which: dpulses,opt is optimized positions of the transmitters in the sequence in which they transmit; dpulses is positions of the transmitters in the sequence in which they transmit; t is transmission instants; VarS is sample variance; and CovS is sample covariance.

Abstract: A method for evaluating obstacles based on locating data of a radar sensor in a driver assistance system for motor vehicles, in which at least one evaluation function is calculated which indicates, as a function of a set of measured variables which are related to a potential obstacle, whether the potential obstacle is to be evaluated as a real obstacle, a complexity indicator being formed based on the locating data which indicates the complexity of a present measurement situation, and at least two different evaluation functions being defined for the same set of measured variables, and it being decided which of the evaluation functions is applied in the present measurement situation as a function of the complexity indicator.

Abstract: System and methods for an application that allows users to interactively create, transform and play music using cell phones, iPhones™ and other enabled mobile communication devices communicating with a remote host are disclosed. Using an enabled mobile communication device, users are able to strike the mobile device like a drum to create and record rhythms, enter melodies using the keypads, add voice recordings, and manipulate musical tracks by tilting the mobile device continuously in three dimensions. The musical input is sequenced in multiple tracks and the transformative manipulations are applied in real time, allowing users to create their songs in an expressive motion-based manner.
