Abstract
The radar system include a plurality of radiating elements arranged in a linear array configured to radiate electromagnetic energy. The radar system also includes a waveguide configured to guide electromagnetic energy between (i) each of the plurality of radiating elements and (ii) a waveguide feed. The radiating elements are coupled to a first side of the waveguide. The radar system additionally includes a waveguide feed configured to couple the electromagnetic energy between the waveguide and a component external to the waveguide. The waveguide feed is coupled to the second side of the waveguide at a position between two of the radiating elements. Further, the radar system includes a power dividing network defined by the waveguide and configured to divide the electromagnetic energy injected by the waveguide feed based on a taper profile.
