Analysis of Radar Cross Section of a Battleship Equipped with an Integrated Mast Module Based on PO and PTD [PDF]
Journal of the Korean Institute of Electromagnetic Engineering and Science, 2017 In this paper, we analyze the radar cross section (RCS) of a battleship equipped with an integrated mast module (IMM). The RCS of a battleship equipped with an IMM is calculated based on physical optics (PO) and the physical theory of diffraction (PTD ...

Analysis of Quantum Radar Cross-Section by Canonical Quantization Method (Full Quantum Theory)
IEEE Access, 2020 This article investigates the difference between two quantum-based theories to calculate the radar cross-section (RCS). Quantum radar cross-section (QRCS) has been commonly analyzed using the dipole approximation method, and the related results show that

Research on Radar Cross Section Measurement Based on Near-field Imaging of Cylindrical Scanning
Leida xuebao, 2015 A new method of Radar Cross Section (RCS) measurement based on near-field imaging of cylindrical scanning surface is proposed. The method is based on the core assumption that the target consists of ideal isotropic scattered centers.

Target scattering characteristics for OAM-based radar
AIP Advances, 2018 The target scattering characteristics are crucial for radar systems. However, there is very little study conducted for the recently developed orbital angular momentum (OAM) based radar system. To illustrate the role of OAM-based radar cross section (ORCS)

Advanced Science, EarlyView.A graphene aerogel with a spherical‐pore structure is constructed via microbubble templating. This unique architecture suppresses strain‐induced percolation of conductive networks, enabling dynamic frequency tuning. It also delivers enhanced low‐frequency absorption with an effective absorption bandwidth of 2.56 GHz, covering 91% of the low‐frequency ...
