Abstract

A method (400) of detecting an object using a radar system is disclosed. The method comprises transmitting (401) a first radar beam having a first frequency and first radiation pattern (301) from an antenna (500), the first radiation pattern comprising a peak at zero azimuth angle, and detecting (402) a first signal from the object due to a reflection of the first radar beam. A second radar beam having a second frequency and second radiation pattern (302) is transmitted (403) from the antenna (500), the second radiation pattern comprising a peak at a non-zero azimuth angle. A second signal due to a reflection of the second radar beam from the object is detected (404), and the first signal and the second signal compared (405) to determine an angular location of the object relative to the zero azimuth angle.
