Analytical expressions are given for the two main effects of ship motion on the detection performance of a sonar: attenuation and distortion of sonar echoes. Regarding attenuation for a ship with an unstabilized transducer, graphs are presented in which the minimum, maximum, and mean loss are plotted as a function of the amplitude of the ship movement. For the distortion, formulas were derived for the maximum frequency spread and optimum length of a tone pulse. On the basis of actual ship motion data, an estimate is made of the optimum pulse length for the worst case situation.
