ABSTRACT:
A method of operating a radar system is shown to include the steps of transmitting a plurality of signals, each signal having a different frequency, and receiving, if existing, a corresponding return signal for each one of the plurality of signals. The method further includes ascertaining an angle off beam cross-over of a target from each existing return signal, selecting the angle off beam cross-over having the largest magnitude, ascertaining a reduction factor appropriate for the selected angle and reducing the magnitude of the selected angle by the reduction factor. With such an arrangement, a radar system is provided having improved elevation measurement accuracy.
