Intelligent Radar Jamming Recognition in Open Set Environment Based on Deep Learning Networks
Remote Sensing, 2022 Jamming recognition is an essential step in radar detection and anti-jamming in the complex electromagnetic environment. When radars detect an unknown type of jamming that does not occur in the training set, the existing radar jamming recognition ...

Software Radar signal processing
Annales Geophysicae, 2005 Abstract. Software infrastructure is a growing part of modern radio science systems. As part of developing a generic infrastructure for implementing Software Radar systems, we have developed a set of reusable signal processing components. These components are generic software-based implementations for use on general purpose computing systems.

Signal design and processing for noise radar
EURASIP Journal on Advances in Signal Processing, 2022 AbstractAn efficient and secure use of the electromagnetic spectrum by different telecommunications and radar systems represents, today, a focal research point, as the coexistence of different radio-frequency sources at the same time and in the same frequency band requires the solution of a non-trivial interference problem.
