Beschreibung
Zusammenfassung:	A radar antenna of the disclosure is a radar antenna unit including a receiving antenna configured to receive a reflected wave of a radar wave. The receiving antenna includes a plurality of receiving antenna elements arranged at an interval so as to form a row along a first direction. The plurality of receiving antenna elements include a first end antenna element positioned at a first end of the row, a second end antenna element positioned at a second end of the row, and a plurality of intermediate antenna elements positioned between the first end antenna element and the second end antenna element. Of a plurality of the intervals between the plurality of receiving antenna elements, at least one interval differs from other interval. The plurality of receiving antenna elements are disposed such that PL+PR≤PAVG×2 holds. PAVG is from 0.8 λ0 to 1.2 λ0. PL is a first end interval.
