Radar Cross Section Measurements of Frequency Selective Terahertz Retroreflectors
نویسندگان
چکیده
The radar cross section of spherical retroreflectors operating at terahertz frequencies is investigated. Several spherical retroreflectors with diameters ranging from 2 mm to 8 mm were fabricated and their radar cross section was measured at 100 GHz, 160 GHz, and 350 GHz. A frequency selective surface was applied to the retroreflectors to demonstrate proof of concept of narrow-band terahertz retroreflection.

Monopole Antenna Radar Cross Section Reduction with Plasma Helix
In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...
متن کاملSensor and Simulation Notes Note 506 January 2006 A Frequency Selective Surface Used as a Broadband Filter to Pass Low-Frequency UWB while Reflecting X–Band Radar
Airborne ultra wideband (UWB) impulse-radiating antennas (IRAs) present an especially large radar cross section to X–band radar. To mitigate this problem, we have numerically and experimentally investigated the use of a frequency selective surface (FSS) as a broadband filter to reflect X–band radar while transmitting lower-frequency UWB signals without loss or dispersion. We present here result...
متن کاملFlexible metamaterial absorbers for stealth applications at terahertz frequencies.
We have wrapped metallic cylinders with strongly absorbing metamaterials. These resonant structures, which are patterned on flexible substrates, smoothly coat the cylinder and give it an electromagnetic response designed to minimize its radar cross section. We compare the normal-incidence, small-beam reflection coefficient with the measurement of the far-field bistatic radar cross section of th...
متن کاملA Low Radar Cross Section Dipole Antenna Simulation
This paper reports a new method for reducing the Radar Cross-Section (RCS) of a metal backed dipole antenna. Numerical simulations are used to show that when the Perfect Electrical Conductor (PEC) is replaced by a carefully designed Frequency Selective Surface (FSS), the electromagnetic performance of the antenna is similar in band, but the RCS of the structure is significantly lower out of ban...
متن کاملA 100 GHz Polarimetric Compact Radar Range for Scale-Model Radar Cross Section Measurements
A fully polarimetric compact radar range operating at a center frequency of 100 GHz has been developed for obtaining radar cross section, inverse synthetic aperture radar imagery and high range resolution profiles on targets and structures of interest. The 100 GHz radar range provides scale-model RCS measurements for a variety of convenient scale factors including W-Band (1:1 scale), C-band (1:...
