Study on Electromagnetic Scattering Characteristics of Ultra-low Altitude Targets above Mountainous Areas

Abstract

In this paper, two typical mountainous areas of valley and hillside with Tomahawk missile above is established by using the composite rough surface modeling method. The fluctuation model with land statistical characteristics is generated based on the Monte Carlo method and Gaussian spectral function. The modified weighted four path model and physical optics (PO) and method of equivalent currents (MEC) are used to calculate the composite electromagnetic (EM) scattering of environment and target. Several useful conclusions are obtained, and the simulation results have a certain reference significance for the detection of ultra-low altitude targets.
