ABSTRACT:
In a radar apparatus, a receiving antenna includes a plurality of antenna elements, each receiving, as a reception signal, radio waves emitted into space and reflected off a target object. An analog signal is obtained by downconverting and putting a bandwidth constraint on the reception signal, and is then converted to a digital signal. Based on the digital signal, a signal processing unit detects the bearing of the target object. The signal processing unit performs processing based on outputs of two sets of the antenna elements.
