Abstract
The report provides an analysis and physical interpretation of the various mechanisms giving rise to radar clutter. Both volume-distributed clutter (rain, chaff, etc.) and surface-distributed clutter (terrain, sea, etc.) are considered. The statistics of the clutter radar cross sections are related to the statistics and properties of the particles or surfaces producing the echoes. The spectral densities of clutter signals are derived in terms of the physical parameters of the clutter sources. Measured results are provided and examples are calculated which indicate the magnitude of the clutter problem for a mid- frequency (S-band) radar system.Keywords
