It is an object to maintain a processing speed while increasing accuracy of a sonar image. Disclosed is a phased-array synthetic-aperture sonar system, including: a plurality of phased array processors (9) which perform, in parallel, phased array processing for a plurality of incoming data; a phased array distribution device (8) which distributes each simultaneously incoming data to the plurality of phased array processors (9), the incoming data being input from a plurality of receivers disposed in a platform; a synthetic aperture processor (11) which performs synthetic aperture processing by using a plurality of phased array processing results; and a data-shaping buffer device (10) which transfers the phased array processing results output from the plurality of phased array processors (9) to the synthetic aperture processor (11) in the order of receipt of the incoming data.
