PROBLEM TO BE SOLVED: To evaluate the quality of a control parameter of an acoustic image apparatus, to simulate with sufficient accuracy an acoustic image acquired by the acoustic image apparatus, and to carry out quantitative performance evaluation of the acoustic image apparatus. SOLUTION: An acoustic image simulation apparatus 10 includes: a sea floor surface forming section 22 which forms a sea floor surface comprised of a plurality of area elements; a condition forming section 23 which forms a condition table that correlates an acoustic source set within a simulation space, a signal receiving position, and an objective area element on the basis of track data of an underwater sailing body or the like; a simulated signal generating section 24 which sets the acoustic source, the signal receiving position, and the objective area element within the simulation space based on the condition table, and which estimates a scattered wave received at the signal receiving position to generate a simulated signal; and a signal processing section 26 which generates an acoustic image of a sea floor surface by using the simulated signal generated by the simulated signal generating section 24.
