  "textContent": "In a radar apparatus, a receiving antenna (12) includes a plurality of antenna elements (121, 122, ...), 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 (20) detects the bearing of the target object. The signal processing unit (20) performs processing based on outputs of two sets of the antenna elements(121, 122, ...).",
