Abstract

The main goal of this article is to investigate the parameters and components influencing the detection of a buried target by a static airborne radar platform by means of loop propagation modeling. In this modeling, the dimensions of the antenna coverage range on the surface and subsurface have been calculated by taking into account all the effective parameters, which allows us to use the radiative transfer theory and determine the amount of input current in each environment, the scattered and absorbed power obtained in the medium. One of the important points in the applications of this type of airborne radars is the proper selection of the central frequency and the frequency bandwidth required for better detection. In this paper, how to choose the parameters of radar design and compromise between having penetration depth and having the resolution are properly presented using delimited diagrams that can be placed as a predefined table in radar memory. Also, with the arrangement of several scenarios, the amount of return signal from the buried target has been measured and verified in CST and GPR_Sim software, and through equations, the depth of its placement has been revealed with an acceptable accuracy of less than 2%.
