Cascaded multiplier-free implementation of adaptive anti-jamming filter based on GNSS receiver

Frontiers in Physics
Evaluating the computational complexity is critical for assessing the time-domain anti-jamming performance of GNSS receivers. The multiplier is the core component that contributes to the computational complexity in time-domain anti-jamming.

GPS ANTI-JAMMING TECHNIQUE USING SMART ANTENNA SYSTEMS

Arid Zone Journal of Engineering, Technology and Environment, 2019
This paper presents a global positioning system (GPS) anti-jamming technique using a smart antenna system. In anti-jamming systems, adaptive array antennas are used to estimate the direction of signals arriving at the antenna and spatially filter the desired signal from the unwanted signals by adaptively controlling the direction of the maximum ...

A Reinforcement Learning-based Intelligent Learning Method for Anti-active Jamming in Frequency Agility Radar [PDF]

Radioengineering
Active jamming's flexibility and variability pose significant challenges for frequency-agility radar (FAR) detection, as it can continuously intercept and retransmit radar signals to suppress or deceive the radar.

An anti-jamming logarithmic receiver

, 1959
Radar receivers presently employed by the Canadian Armed Services are little use against chaff drops, or spot and slow-sweep electronic jammers, which almost invariably cause the receivers to saturate. A logarithmic receiver is a useful ECCM device in an air-defence radar set subjected to this jamming.
