    Abstract: PURPOSE: A towed array sonar and a target direction detecting method are provided to accurately detect a direction of a target by revising direction error of the target. CONSTITUTION: A towed array sonar comprises a plurality of acoustic sensors(100), a target probe(200), and a direction compensator(300). The plurality of acoustic senses receives an acoustic signal by linearly being arranged. The target probe detects a target signal from the acoustic signal and outputs target direction and target distance. The direction compensator revises an error of the target direction based on arrival angle of sound rays according to a transmission route of a target signal. [Reference numerals] (100) Acoustic sense; (210) Signal processor; (220) Beam generator; (230) Signal detector; (300) Direction compensator; (AA) Target direction and target distance
