IMAGING RADAR SYSTEM HAVING A RECEIVING ARRAY FOR DETERMINING THE ANGLE OF OBJECTS IN TWO DIMENSIONS BY MEANS OF A SPREAD ARRANGEMENT OF THE RECEIVING ANTENNAS IN ONE DIMENSION

摘要

The present invention relates to an apparatus for determining the position of objects in two-dimensional space having a first dimension and a second dimension, the direction vector of which is orthogonal to the direction vector of the first dimension, containing at least one transmitter (1) having at least one transmitting antenna (3) and an imaging receiver circuit (2) having at least one receiving antenna array (Rx Array) with rows (6) of receiving antennas for scanning the first dimension by means of digital beam shaping, wherein the receiving antenna array has a linear array, a sparse array or an array with an enlarged aperture, and wherein the rows (6) of receiving antennas in the receiving antenna array of the receiver circuit (2) are linearly arranged in the first dimension according to a curve function or according to the contour of a two-dimensional geometric object and are spread out in the second dimension, and to a method using the apparatus.
