ABSTRACT:
A radar device radiates and receives radio frequency energy pulses using an antenna having two independently driven major lobes. The two major lobes aim in two separate directions, and a third direction halfway between the two directions exhibited by the two major lobes represents an aim line of the apparatus. The antenna selectively radiates both circularly and linearly polarized pulses. Reflections received from circularly and linearly polarized pulses are compared to prevent a false indication of an object's centroid.
