Analysis of Radar Detection Range Based on Parabolic Equation Method Considering Atmospheric Refractivity and Actual Terrain

This paper proposes a method for analyzing radar detection range based on the parabolic equation technique considering atmospheric refractivity and actual terrain effects. While previous studies using parabolic equation techniques were primarily limited to analyzing wave propagation characteristics in two-dimensional distance-height planes, this research extends the analysis by performing sequential calculations along azimuth angles to reflect actual radar operating environments. The proposed method can precisely reflect the effects of actual terrain using topographical data of the western coast of Korean Peninsula provided by NASA, and enables accurate radar detection range prediction by simultaneously considering atmospheric refractivity and earth curvature effects.
