Imaging radar system with a receiving array for the angular determination of objects in two dimensions by a spread arrangement of receiving antennas of one dimension

摘要

The present invention relates to a device for determining the position of objects in two-dimensional space having a first dimension and a second dimension whose direction vector is orthogonal to the direction vector of the first dimension, comprising at least one transmitter (1) with at least one transmitting antenna (3). and an imaging receiver circuit (2) having at least one receive antenna array (Rx array) with receive antenna lines (6) for first dimension sampling by digital beamforming, the receive antenna array having a linear array, a sparse array or an enlarged aperture array, and wherein Receive antenna lines (6) of the receiving antenna array of the receiver circuit (2) in the first dimension according to a curve function or according to the contour of a two-dimensional geometric object are linearly arranged and spread in the second dimension, and a method using the device.
