A full-scale static radar cross-section (RCS) measurement facility [PDF]
, 2007 We present an overview of a full-scale static RCS near-field measurement facility, and some sample measurements. The measurements, and the target, are in the near-field RCS range. Corrections for distance are made using sophisticated software.

Ultra Wide Band Near-Field 3-D Radar Cross Section (RCS) Holography
, 1993 RCS impulse holography is a new concept for obtaining near-field, three-dimensional RCS measurements and low-observable diagnostic image reconstructions. The high-resolution images (holographic reconstruction) maps the target’s scattering areas and identifies the “hot spots” at each frequency (i.e., in the pulse bandwidth) which dominate the far-field ...

Measurement of Nonlinear RCS of Electronic Targets for Nonlinear Detection [PDF]
Journal of Electromagnetic Engineering and Science, 2022 The conventional radar technology is based on linear detection—i.e., the same transmit and receive frequencies are used. However, with linear radars, difficulties arise when detecting electronic objects with relatively small radar cross section (RCS). To

X-Band Radar Cross-Section of Tandem Helicopter Based on Dynamic Analysis Approach
Sensors, 2021 In order to study the radar signature of a tandem helicopter in the X-band, a dynamic analysis approach (DAA) is presented to determine its radar cross-section (RCS) under different influence factors.

Generalized Radar Range Equation Applied to the Whole Field Region
Sensors, 2022 Most terahertz (THz) radar systems can only work in the near-field region, because the THz source power is limited and the size of the target scattered near field is up to tens of kilometers.

Sensors, 2020 Radar cross section near-field to far-field transformation (NFFFT) is a well-established methodology. Due to the testing range constraints, the measured data are mostly near-field.

Measurement and evaluation of radar cross section for furniture in an indoor propagation channel [PDF]
Advances in Radio Science, 2014 This paper has attempted to evaluate the radar cross section (RCS) of two furniture items in an indoor environment in a frequency range of 3–7 GHz of the ultra-wideband (UWB) range.
