Abstract

A radar arrangement, for example a frequency modulated continuous wave (FMCW) radar arrangement, is provided with an antenna array which is operated off-boresight in order to provide beam scanning. The antenna array comprises a plurality of antenna elements (16.1 - 16.10) which are arranged to produce a wavefront which is inclined relative to the final scanning direction. The inclined wavefront is produced either by inclining the antenna elements (16.1 - 16.10 (Figure 6 - not shown)) or using prismatic elements (20.1 - 20.14 (Figure 4A)). A beam deflecting prism (22) produces a scanning wavefront which is propagated in the desired direction.
