Automotive radar with end-fire antenna fed by an optically generated signal transmitted through a fiber splitter to enhance a field of view

摘要

A vehicular radar system includes an optical source designed to output an optical signal. The vehicular radar system further includes a first optical splitter coupled to the optical source and designed to split the optical signal into a first duplicate signal and a second duplicate signal. The vehicular radar system further includes at least one converter coupled to the first optical splitter and designed to convert the first duplicate signal and the second duplicate signal into a first radar signal and a second radar signal, respectively. The vehicular radar system further includes a first antenna coupled to the at least one converter and designed to transmit the first radar signal, and a second antenna coupled to the at least one converter and designed to transmit the second radar signal.
