The target strength which characterizes the reflectivity of a marine tech-nical object, depends on a number of factors. In the article, only some of them are analyzed, namely, the effect that geometric dimensions of a hull, course angles, the speed of an object, the location distance and frequency have on the value of the target strength of an object. The averaged values of the characteristics of the secondary hydroacoustic field for an ellipsoid of rotation, simulating the hull of a technical object, are presented, de-pending on its displacement, shape and dimensions. The comparison method is discussed, which makes it possible to determine the target strength of small ships within short distances and ships with large dis-placement. The data from public sources on the ballpark values of the tar-get strength of the US and NATO marine technical objects for the sonar frequency range of 3 to 20 kHz at the traverse and sharp course angles are given.
Keywords:target force, secondary hydroacoustic field, reflected signal, marine technical object, comparison method.
