Selection of the proper frequencies that are able to detect civil and military aircrafts is a challenging issue in radar engineering. Proposed algorithm measures the effect of the linear polarization including H-wave polarization on the radar detection behavior in random medium, and hence, compares it with the E-wave polarization case. Effects of random medium properties on the scattered waves are analyzed. In doing this, laser radar cross section (LRCS) of targets is calculated using a boundary value method with a beam wave incidence. As a result, performance of the backscattering enhancement is studied with the object configuration considering the creeping waves that have an obvious impact, particularly in the resonance region.
