Summary

 
Object and purpose of research.The paper investigates the effect of the underlying surface upon the radar reflection from a multi-element scattering target. It discusses the changes in statistical and spectral scattering parameters due to the underlying surface.
Subject matter and methodsThis study applies a statistical approach to the problem of electromagnetic wave scattering on lengthy bodies developed in the 1970s by V. Kobak and M. Varshavchik (Krylov Shipbuilding Research Institute). The target is represented by a multi-element model, i.e. a totality of the rigidly interconnected point reflectors (hot spots) randomly arranged in a certain space. Statistical properties of the peaks coming out of the enveloping curve describing the scattered field are also determined by means of this multi-element model.
Main results.This paper provides an estimate of how much the underlying surface increases the radar scattering from a naval target: the study has shown that the power of the reflected signal grows by six times. The paper also provides a quantitative assessment of the increase in the number of the back-scattering diagram beams: this number increases in proportion of the target elevation over the sea
Conclusion.This paper is a further development of the theoretical studies in the statistical radar detection and ranging pursued by the leading scientists of Krylov Centre back in the 1970s. It provides quantitative estimates for the increase in the electromagnetic backscattering due to the underlying surface. These results could be used to assess the optimal elevation of the decoy target (dipole cloud) in case of anti-ship missile attack.
