Zusammenfassung:	The invention discloses a passive radar direction-finding method and system based on dual receiver elliptical scanning. The passive radar direction-finding method includes: acquiring a first echo signal of a first receiver; acquiring a second echo signal of a second receiver, and constructing a first signal recognition matrix according to a motion trajectory function of the first receiver; determining a first direction-finding preprocessing vector according to the first echo signal and the first signal recognition matrix; constructing a second signal recognition matrix according to a motion trajectory function of the second receiver; determining, according to the second echo signal and the second signal recognition matrix, a second direction-finding preprocessing vector; determining the direction of the object to be tested according to the first direction-finding preprocessing vector and the second direction-finding preprocessing vector. The method adopts the elliptical scanning mode,can finely distinguish a
