Abstract

Abstract:

In response to the terrain masking problem commonly encountered in airborne electronic warfare, a quantitative analysis method was conducted on the impact of electromagnetic wave diffraction with shielding conditions on airborne electronic warfare equipment. At first, based on traditional unimodal knife-edge diffraction model, an algorithm for calculating peak diffraction height was proposed. Then, based on Picquenard mutimodal knife-edge diffraction model, an iteration algorithm for searching main peak under earth curvature was proposed. Finally, the counter measures of airborne electronic warfare under terrain shielding condition was presented. After embedding the algorithm into the model, by comparing simulation results with real experimental data, it is shown that the proposed algorithm is suitable for calculating the impact of terrain occlusion on airborne electronic warfare equipment.

Key words: terrain shielding, electromagnetic wave diffraction, airborne electronic warfare, electronic counter
