The invention provides a double-station radar combined target positioning method and system. The double-station radar combined target positioning method comprises the following steps of: 1, acquiringtwo radar stations, a three-dimensional measurement result of a target and measurement error statistical parameters under a North Tiandong measurement coordinate system; 2, respectively solving uncertain ranges of target measurement caused by azimuth and pitch measurement errors of the two radars, respectively making a spherical surface by taking station addresses of the two radars as circle centers and distance measurement of the radars as radiuses, solving an intersection line of the uncertain ranges and the spherical surfaces, and then taking midpoints to obtain two intermediate results; and 3, averaging the two intermediate results to obtain a combined positioning result. The method is suitable for compression filtering processing in medium and long baseline configuration multi-radar collaborative centralized
