“…However, this can give significant errors in the case that BSP has many sharp highlights corresponding to specular reflections from different parts of the object. So, we can consider the obtained data without any approximations as a sum of delta functions which have peaks in the points corresponding to the calculated RCS values σ i and have amplitudes 1/N (the probability to obtain RCS value σ i ) [23]:…”

“…However, technique mentioned above supposes re-calculation for each new background surface (with other electromagnetic characteristics). In order to circumvent this difficulty, the following method was proposed by authors in [23]. In this case, the full scattered field for on-ground object is presented in the form of series over powers of background surface reflection coefficient.…”

Abstract-Nowadays it is important to create military and civilian vehicles which would be invisible to radar (or homing precision weapons). Such a task requires using high amount of radio-absorbing materials and high cost of finished samples of re-engineering. So it is very useful to have some methods for mathematical modeling of electromagnetic waves scattering on the object in order to take into account various techniques to reduce the object visibility at the stage of design. After the mathematical modeling for each case (specified wavelength, polarization, background surface, etc.), we obtain the angular RCS dependence. We obtain such dependencies for two different models. Based on the comparison of these two dependencies for different objects, it is very difficult to determine which one of the objects is more detectable. This paper presents a new calculation method which allows characterizing the scattering properties of each object only with a few numbers: specific RCS (same as normalized RCS) and RCS dispersion. The presented method can be simply used to assess the visibility of the objects placed on different background surfaces.
