Patent ID: 10187134

Abstract:
A method for transmit beamforming in a MIMO antenna for a radar system having N transmit antennas includes acquiring a coding matrix defining a desired field-of-view, generating a transmit signal matrix based on a singular value decomposition (SVD) of the coding matrix, wherein the columns of the transmit signal matrix are transmit signal vectors formed from the singular vectors corresponding to the maximal singular values of the coding matrix based on the SVD, the transmit signal vectors defining spatial codewords, and transmitting signals in sequences over the N transmit antennas according to the transmit signal matrix, the sequences correspond to the spatial codewords from the transmit signal vectors, wherein each sequence is defined by a number of spatial codewords transmitted in a single repetition sequence interval, and wherein transmitting the spatial codewords according to the transmit signal matrix enables beamforming of the transmitted signals to the desired field-of-view.
