Detection and Identification of Multipath Jamming Method for Polarized Radar Seeker

Leida xuebao, 2016
Multipath jamming is an effective self-defense jamming mode used to counter airborne fire-control radar or radar seekers. Multipath jamming has a deceptive jamming effect on the range, velocity, and angle of radar, making it difficult to identify and ...

Numerical Studies of Influencing Factors on the Homogeneity of the Powder Mixture during the Powder Spreading Process of Powder Bed Fusion–Laser Beam/Metal

Advanced Engineering Materials, EarlyView.
AISI 304L stainless steel powder is mixed with silicon nitride (Si3N4) powder and processed by PBF‐LB/M, allowing partial retention of Si3N4. The numerical approach effectively predicts the Si3N4 powder homogeneity and N content distribution on the powder bed. Recent studies have focused on the alloying of nitrogen (N) in high‐alloy stainless steels by

Analysis of MSK jamming effectiveness based on effective jamming coefficient

Tongxin xuebao, 2022
For the problem of communication jamming effectiveness, an effective jamming coefficient was proposed as an evaluation metric based on the correlation between jamming and communication signals, and the impact of orthogonal receivers was analyzed ...

The Study on Characteristic Blanking Technique in Frequency Shifting Jamming for LFM Radar

Leida xuebao, 2012
Shift-frequency jamming is an effective jamming to the Linear Frequency Modulation (LFM) radar. However, the feature of carrier frequency offset of the traditional shift-frequency jamming may be used to identify the jamming signal.

Bioinspired Design of Isotropic Lattices with Tunable and Controllable Anisotropy

Advanced Engineering Materials, EarlyView.
This study introduces nested isotropic lattices, integrating architectural elements like nesting orders and orientations inspired by bioarchitectures. The design enables tunable anisotropy across nine mono‐nest and twenty multi‐nest lattices with 252 parametric variations, demonstrating transitions from shear‐ to tensile‐compression‐dominant behaviors ...

An Anonymous Channel Categorization Scheme of Edge Nodes to Detect Jamming Attacks in Wireless Sensor Networks

Italian National Conference on Sensors, 2020
Wireless Sensor Networks (WSNs) are vulnerable to various security threats. One of the most common types of vulnerability threat is the jamming attack, where the attacker uses the same frequency signals to jam the network transmission.
