Image radar system with a receiving array for determining the angle of an object in two dimensions by a one-dimensional diffusion arrangement of the receiving antenna

摘要

The present invention relates to an apparatus for determining the position of an object in a two-dimensional space having a first dimension and a second dimension, and a method using the apparatus, wherein the direction vector in the second dimension is orthogonal to the direction vector in the first dimension , One or more transmitter antennas (Rx arrays) with one or more transmitter antennas (1) with one or more transmit antennas (3) and columns of receive antennas (6) for scanning the first dimension by digital beamforming. Includes an image receiver circuit 2, wherein the receiving antenna array has a linear array, a sparse array, or an array with an enlarged aperture, and also the receiving antenna of the receiving antenna array of the receiving circuit 2 The columns of fields 6 are arranged linearly in the first dimension according to a curve function or along the contour of a two-dimensional geometric object.
