摘要： The invention describes a radar method for the coherent evaluation of radar signals in a radar system, in particular a multistatic radar system, wherein at least one or a plurality of received signals is/are received in several signal channels of an antenna arrangement, and wherein a synthetic received signal of a virtual transmitting and receiving antenna is generated using at least one composition model on the basis of the one or more received signals.
The invention further describes a radar system according to claim 9 as well as a use of the radar system according to claim 14.
The invention enables coherent evaluation of radar signals without the need to use a reciprocal signal propagation channel between the participating radar units of the radar system.-

摘要： Estimating the ego-motion of a vehicle, e.g., the self-motion of the vehicle, can be improved by pre-processing data from two or more radars onboard the vehicle using a processor common to the two or more radars. The common processor can pre-process the data using a velocity vector processing technique that can estimate a velocity vector at each point of a predefined number of points, such as arranged in a grid in the field-of-view of radars, with coordinates (X, Y, Z (optional)), where U is the component of the velocity in the X-direction, V is the component of the velocity in the Y-direction, and W is the component of the velocity in the optional Z-direction.

摘要： The invention relates to a radar system for capturing surroundings of a moving object, in particular a vehicle and/or a transportation apparatus, such as a crane, in particular, wherein the system is mounted or mountable on the moving object, wherein the radar system comprises at least two non-coherent radar modules (RM 1, RM 2, . . . RM N) having at least one transmitter antenna and at least one receiver antenna, wherein the radar modules (RM 1, RM 2, . . . RM N) are arranged or arrangeable in distributed fashion on the moving object, wherein provision is made of at least one evaluation device which is configured to process transmitted and received signals of the radar modules to form modified measurement signals in such a way that the modified measurement signals are coherent in relation to one another.
