Book Overview: Radar Cross Section

Title: Radar Cross Section Authors: Eugene F. Knott, John F. Shaeffer, Michael T. Tulley Publisher: SciTech Publishing (originally Artech House) Editions: 1st Edition (1985), 2nd Edition (2004)

Legacy and Conclusion

The PDF version of Radar Cross Section by Eugene F. Knott, John F. Shaeffer, and Michael T. Turley remains a ubiquitous resource on the hard drives of defense contractors and university labs alike. It bridges the gap between Maxwell’s equations and the practical realities of stealth technology. radar cross section eugene f. knott pdf

Key RCS Concepts to Know

• Monostatic vs. bistatic RCS: Monostatic RCS refers to co-located transmitter and receiver; bistatic involves separated transmitter and receiver and generally yields different scattering behavior.
• Aspect dependence: RCS can vary by orders of magnitude with orientation—flat plates, edges, and corner reflectors show strong angular dependence.
• Frequency and polarization: Different frequencies probe different target scales; polarization affects which scattering mechanisms dominate.
• Coherent vs. incoherent mechanisms: Specular reflection, diffraction, surface waves, and resonance all contribute in ways that may add coherently or incoherently.
• RCS units and interpretation: RCS is expressed in square meters (often in dBsm). A small RCS does not always mean “invisible”—it depends on radar sensitivity, range, and environmental clutter.

b. Historical Context

The book includes rare historical notes on RCS research from World War II (MIT Rad Lab), through the Cold War (Lockheed Have Blue, F-117 development), up to modern stealth platforms. Knott personally knew many pioneers, lending authority. Book Overview: Radar Cross Section Title: Radar Cross

Significance in the Field

Before the publication of this text, comprehensive information regarding Radar Cross Section (RCS) was scattered across academic journals, classified military reports, and obscure technical memos. Knott and his co-authors consolidated this knowledge into an accessible format. Monostatic vs

• Use wavelength-based meshing: ~λ/10–λ/20 for full-wave; coarser for PO but refine near edges and curvature changes.
