Quantum radars expose stealth planes
Engineering & Technology, 2019Stealth planes currently go under the radar, figuratively speaking, but maybe the higher definition promised by quantum radars could be used to expose them. Radar technology has become an ever more important tool in warfare since the Second World War, used to monitor the electromagnetic spectrum to detect and track enemy aircraft, missiles, satellites ...

Nonsinusoidal radar signal design for stealth targets
IEEE Transactions on Electromagnetic Compatibility, 1995The detection of stealth point targets challenges the design of conventional radars using sinusoidal carriers since the objective of stealth technology is to reduce the radar cross section (RCS) of targets to a level where the radar receiver cannot detect the target.

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.

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 MaterialsAbstract Inspired 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 ...
