RÉSUMÉ

On the basis of the developed by the authors of [1,2] method for calculation of the secondary radiation from the ground-based objects (possibly with the radar absorbing coatings) it is created the algorithm of partial coating of the object with the radar absorbing material (the "camouflage") in a way that the value of the average effective scattering cross-section (ESCS) of the object within the given angular range of irradiation is maximally close to the average ESCS of the "shadowed" by the object section of the substrate (background) surface. Therefore, the developed method allows making the object maximally invisible ("non-contrast") for the means of radar survey. Relevant calculations for angular ranges of the irradiation and the substrate surface with different level of roughness are provided for the tank model.
