Abstract :
Coastal HF radar in the ground-wave mode may be useful for monitoring the movement of ships, aircraft, and icebergs over vast areas of ocean. At HF frequencies an aircraft is in the `resonance range´ of size. The radar cross section (RCS) of four fuselage-like scatterers of resonant size, illuminated end-on (noise-on for the aircraft), and broadside is studied. The RCS is determined both by direct measurement and by wire-grid modeling, with good agreement. The RCS is studied as a function of frequency for scatterer lengths from 0.5λ to 3.5λ. The RCS behaves quite differently for end-on incidence than for broadside incidence
