Definitions

  • radar sensors are increasingly being used for more and more tasks. For example, they provide data from the surroundings of a vehicle, which are evaluated and evaluated by a driver assistance system
  • UWA Uniform Linear Array
  • FFT fast Fourier transform
  • the publication DE 10 2011 084 610 A1 discloses an angle-resolving radar sensor for motor vehicles with one antenna, which has several
  • Each antenna element can be switched to one of several evaluation channels and is coupled to an evaluation device for determining the angle of incidence of a received signal.
  • a device for evaluating radar signals, in particular a plurality of radar signals, which have been received by an antenna array comprises a first processing device, a second processing device and an evaluation device.
  • the processing device is designed to apply a second beam shaping to a radar signal of the plurality of radar signals, the second beam shaping being different from the first beam shaping.
  • Evaluation device is designed to determine the received radar signals using the results of the first beam shaping and the second
  • a radar signal is to be understood as the sum of all signals of the individual reception channels of the individual antenna elements of the antenna array.
  • a radar system is used regularly, preferably periodically, Send out high-frequency signals that are reflected by an object to be detected, and the reflected signals can then be received by the antenna elements of the antenna array and made available in the individual receiving channels for further processing.
  • the multiple transmission of high-frequency signals and the reception of the corresponding radar responses also result in several
  • the first beam shaping and the second beam shaping are applied to different radar signals.
  • the application of the first beam shaping and / or the application of the second beam shaping are carried out by applying a complex window function.
  • Such complex window functions enable particularly simple and efficient adaptation of the beam shaping to the respective requirements.
  • the beam shaping can be carried out particularly efficiently by means of a fast Fourier transformation.
  • Figure 1 is a schematic representation of a block diagram of a
  • Figure 2 is a schematic representation of the antenna gain according to the
  • FIG. 3 shows a schematic illustration of a flow chart as it is based on a method for evaluating radar signals according to one embodiment.
  • the emitted signals can be reflected on an object O.
  • the reflected signals are then received by the antenna elements 2-i and provided on the device 1 for evaluating the radar signals. This is used as a radar signal in this
  • Processing device 12 and an evaluation device 13 The first
  • the digital beam shaping of the radar signal can be any digital beam shaping of the radar signal.
