Radar Cross Section Eugene F. Knott Pdf

Eugene F. Knott ’s seminal work, Radar Cross Section , co-authored with John F. Schaeffer and Michael T. Tuley, is the definitive resource for understanding the echo characteristics of objects scanned by radar. First published as a set of course notes at Georgia Tech in 1983, the material was expanded into a comprehensive textbook that covers the prediction, measurement, and reduction of radar cross section (RCS).

Common RCS features and physical origins Eugene F

Eugene F. Knott is primarily known for his seminal work, Radar Cross Section Specular peaks: from large flat facets oriented toward

  • Specular peaks: from large flat facets oriented toward the radar (optical reflection).
  • Edge diffraction lobes: from sharp edges and tips—often modeled by UTD.
  • Resonances: cavity modes, internal resonances (e.g., open cavities, engine inlets), produce narrowband peaks in frequency.
  • Corner/trihedral reflectors: produce very large RCS when oriented toward the radar (three mutually orthogonal reflecting surfaces).
  • Surface roughness scattering: diffuse scattering increases RCS off-specular directions and depends on rms roughness relative to λ.
