Hayre, Harbhajan S.2022-09-232022-09-231968196813810899https://hdl.handle.net/10657/11909Previous flight experiments have shown that spectrum compression is affected by terrain surface roughness. In order to determine, the terrain effect on wide bandwidth radar systems, a comparative analysis is performed on the methods of pulse and spectrum compression. The sampling theorem is used to define a spectrum compression ratio which discloses the dependence on the spectral width and shape of the uncompressed doppler spectrum. Furthermore, in order to accent the surface effects on the doppler signal, a low altitude flight experiment was planned and conducted under the authors direction. A narrow-beamwidth doppler radar was used for the spectrum analysis. A wide-beamwidth doppler scatterometer was used for the corresponding variations in radar backscattering cross-section.
