An investigation of bistatic calibration objects [PDF]
Several popular metallic bistatic calibration objects are investigated, including a sphere, long and short cylinders, dihedral, trihedral, circular disk and wire mesh. Comparisons are made between the advantages and disadvantages of various objects for calibration.

Optimized Ni nanoparticle loading on reduced graphene oxide creates abundant Ni/rGO heterointerfaces, enhancing interfacial polarization, conductive loss, magnetic loss, and impedance matching. The rGO/Ni‐5 hybrid achieves efficient microwave absorption at only 15 wt.% filler loading, delivering a minimum reflection loss of −35.5 dB and an effective ...

An Anti-2D Deceptive Jamming Method for Bistatic SAR Based on Jammer Localization
Synthetic aperture radar (SAR) is an essential instrument for Earth observation but is vulnerable to intentional electromagnetic jamming during imaging. Two-dimensional (2-D) deceptive jamming can introduce highly realistic false targets into SAR images,

The Calculation and Analysis of the Bistatic Quantum Radar Cross Section for the Typical 2-D Plate
The quantum radar cross section (QRCS) describes how much return one gets when illuminating an object with a handful of photons. However, the previous studies mainly focused on the monostatic scattering of quantum radar.

First steps to bistatic focusing [PDF]
Although this work is a bit theoretical and contains lots of derivations, it leads to very explicit practical results in bistatic focusing. Our approach is based on Loffelds bistatic formula describing the point targets reference spectrum for arbitrary bistatic configuration.

Analytically Co‐Designed Absorption‐Diffusion Coding Metasurface for RCS Reduction
ABSTRACT This work proposes a novel and simple design method for an absorption‐diffusion metasurface, combining a coding diffusion‐type metasurface with an absorbing layer. The diffusion and absorption properties are obtained through an analytical co‐design methodology derived from a straightforward Smith chart‐based construction.

A Multiple Interference Suppression Algorithm Based on Airborne Bistatic Polarization Radar
To solve the problem of the simultaneous suppression of main-lobe and side-lobe interferences, this study applies polarization information as input to the airborne bistatic radar and constructs an airborne bistatic polarization-sensitive array.

An investigation of bistatic calibration techniques [PDF]
Several popular bistatic calibration techniques are investigated and comparisons made between the relative merits of the various techniques. The analysis addresses sensitivity to object alignment error, sensitivity to polarization impurity, and ease of implementation.

ABSTRACT Pingos are large mounds with cores formed of intrusive ice that form in periglacial landscapes. These ice structures can form in regions of discontinuous permafrost, commonly as hydraulic or open‐system pingos, or in locations of continuous permafrost, commonly as hydrostatic or closed‐system pingos.
