Abstract
Influence of the half-space background on radar signatures of small consumer drones have been investigated in this paper. An integral equation method is presented to calculate the reflections of small drones within a half-space background efficiently and accurately, accelerated by the multilevel fast multiple algorithm. In addition, a two-level discrete complex image method has been applied to speed up the calculations of Sommerfeld integrals existing in the conventional half-space Green's functions. Variations of reflections as a function of variables such as polarization and frequency are explored for free space and half space respectively. Scattering data are also post-processed into two dimensional inverse synthetic aperture radar (ISAR) images to investigate the influence of half-space background further.
