Radar Cross Section of Naval Targets In the HF Domain

This paper aims to evaluate the radar cross section of naval targets in the HF domain. This calculation requires the knowledge of the incident field at the target location which, in the case of a vessel, is modified by the wave propagation at the air-sea interface for a ground wave propagation and by the ionosphere for a sky wave propagation. The paper presents the calculation of the incident field radiated by the transmitting antenna, then the field propagated towards the vessel and finally the radar cross section.
