Active cancellation stealth analysis of warship for LFM radar
IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS, 2010Active stealth of warship is an important developing direction in modern stealth technology field. Based on scattering properties of warship and characteristics of linear frequency modulated (LFM) signal and its matched filter, the cancellation signal was designed.

Countering stealth with passive, multi-static, low frequency radars
IEEE Aerospace and Electronic Systems Magazine, 2010The potential of passive, multi-static radars as covert sensors for the detection of low flying, stealth air targets are illustrated by multi-static RCS analysis, coverage simulations for low flight levels and measurement results obtained with an experimental passive radar using digital audio broadcast signals (DAB). The measurement sensor is described

Adaptive RF stealth beamforming for frequency diverse array radar
2015 23rd European Signal Processing Conference (EUSIPCO), 2015This paper proposes an adaptive radio frequency (RF) stealth beamforming for frequency diverse array (FDA) radar using spoiled frequency increments. Since active radars are highly visible to intercept receivers, traditional high-gain phasedarray antenna beam is replaced by a series of low-gain FDA beam with nonlinear frequency increments to reduce the ...

Biomimetic Water‐Based Metamaterial Absorber for Ultrabroadband Radar Stealth
Advanced MaterialsAbstractInspired by the hierarchical porous architecture of Pachliopta aristolochiae butterfly wings and leveraging the intrinsic dielectric dispersion of water, it proposes a biomimetic water‐based metamaterial absorber. Breaking conventional compactness‐bandwidth trade‐offs, this work integrates aqueous metamaterials with bio‐inspired architecture ...

Radar Cross Section measurements on the stealth metamaterial objects
2011Absorbing metamaterials (MM) offer the exciting possibility of near-unity absorption at specific resonance frequencies where the characteristic impedance Z(ω) is designed to match the free-space impedance and the imaginary part of the refractive index κ(ω) is as high as possible.
