| Zusammenfassung: | The invention discloses a circumferential and simple harmonic composite scanning passive radar direction finding method. A double-circumference composite scanning receiving system is adopted, the motion trail of a receiver is more complex than the circular motion trail of an existing receiver rotation direction finding technology, and through composite scanning, the effective receiving area of thereceiver is changed into an annular area with the inner diameter being r-1 and the outer diameter being r+1 from the circumference with the radius being r. Therefore, the effective data receiving area of the receiver is enlarged, and the received effective echo data is richer. Therefore, the circumferential and simple harmonic composite scanning passive radar direction finding method provided bythe invention can reduce the sidelobe height of the direction finding result, and greatly reduces the cost compared with a double-receiver direction finding system.
