Patent ID: 11843162

Abstract:
A multiple-input multiple-output, MIMO, radar system for detecting an object in a vicinity of an aerial vehicle, includes a first transmitter patch, a second transmitter patch, and a third transmitter patch. Each transmitter patch has, respectively, a first, second, and third plurality of transmitting antenna elements configured to transmit, respectively, a first, second and third plurality of transmission signals. The MIMO radar system further includes a plurality of receiving antenna elements, wherein each receiving antenna element is configured to receive the transmitted transmission signals after their reflection from the object. The MIMO radar system further includes a signal forming module, configured to generate the transmission signals and to provide the transmission signals to their respective transmitting antenna elements. The MIMO radar system further includes a digital processing module, configured to detect, based on the received transmission signals, characteristics of the object. A first direction between the first transmitter patch and the second transmitter patch is different from a second direction between the second transmitter patch and the third transmitter patch. Also, each transmitter patch includes multiple transmitting antenna elements in the first as well as in the second direction. With this, a virtual array of receiving antenna elements which extends the plurality of receiving antenna elements in the first and in the second direction in a gap-free and homogeneous way is achieved.
