Abstract

This chapter introduces a novel software tool (PETOOL), which is developed in MATLAB with graphical user interface (GUI) for the analysis and visualization of radio wave propagation through the homogeneous and inhomogeneous atmosphere, by incorporating variable terrain effects with the aid of the two‐way split‐step algorithm employing wide‐angle propagator. The PE method handles only the forward‐propagating waves and neglects the backscattered waves. The forward waves provide almost accurate results for typical long‐range propagation problems, only if there does not exist obstacles that redirect the incoming wave in the form of reflections and diffractions. PETOOL software package has been developed in MATLAB with a user‐friendly GUI for the analysis and visualization of radio wave propagation. The user should be able to easily specify range dependent or range independent refractivity profiles by just selecting from a list of various types of atmosphere profiles.
