The analysis of the phonotarget situation is the basis for development of radar means. Development of Stealth technology goes, generally in two directions: developments of architecture and the radio absorbing materials. It is also necessary to consider influence of the uneasy sea surface. The aforesaid results in considerable difficulties of receipt of identical objects for experimental methods of the research of the radar signature. Vendors of the radio absorbing materials do not focus attention on influence of coefficient of reflection from descent angle and the frequency of radio waves that leads to consider-able errors of calculation methods of assessment of radar characteristics. Development of the complex automated technique of assessment of radar characteristics of offshore facilities on their radiophysical 3D-models taking into account influence of the sea and angular dependences of coefficient of reflection. The main aspects of creation of the complex method of calculation of parameters of the radar signature different from the known method of local sources on air or on the surface object are stated. The technique is free from the restrictions demanding the flat falling field. Conditions of rereflections from the sea surface and feature of Stealth technologies on the outside surface and in open cavities are considered. The technique is verified according to measurements in the conditions of the anechoic camera with the water basin. The received results are used for assessment of the phonotarget situation for development of radar-tracking systems for the benefit of Navy.
