Analysis of Space-Based Radar Clutter Spectra Over Different Types of Terrain and Their Effects on Detection Performance
A computer model was used to make a detailed analysis of the clutter spectra received by real aperture Space-Based Radars orbiting over different types of terrain. The influence of terrain on L-band SBR detection performance has also been studied. It was found that the clutter spectra tend to become...
