Abstract
A method for a radar sensor for a motor vehicle, for angle estimation of radar targets based on an antenna diagram that indicates, for various configurations of radar targets, pertinent amplitudes and/or phase correlations between signals which are obtained for the relevant configuration in multiple evaluation channels of the radar sensor, wherein for a single real target, the occurrence of a number n of apparent targets, which are caused by reflection of the signal coming from the real target from elongated objects, is modeled mathematically; a correlation between the location angle of the real target and the location angles of the apparent targets is calculated; and to estimate the location angle of the real target, a multi-target estimate is performed in an n-dimensional search space and the search is limited to a sub-space that is determined by the calculated correlation.
