Dual-functional microwave photonic system for concurrent radar and secure communication via radar signal masking [PDF]

arXiv
Integrating functions such as radar and communication into a single system is of great significance for the miniaturization and functional integration of future electronic warfare and 6G systems. Here, we show a dual-functional microwave photonic system for concurrent radar and secure communication.

Precise Interception Flight Targets by Image-based Visual Servoing of Multicopter [PDF]

arXiv
Vision-based interception using multicopters equipped strapdown camera is challenging due to camera-motion coupling and evasive targets. This paper proposes a method integrating Image-Based Visual Servoing (IBVS) with proportional navigation guidance (PNG), reducing the multicopter's overload in the final interception phase.

How Close Can I Be? - A Comprehensive Analysis of Cellular Interference on ATC Radar [PDF]

arXiv, 2017
Increasing data traffic demands over wireless spectrum have necessitated spectrum sharing and coexistence between heterogeneous systems such as radar and cellular communications systems. In this context, we specifically investigate the co-channel coexistence between an air traffic control (ATC) radar and a wide area cellular communication (comms ...

Efficient Radar Modulation Recognition via a Noise-Aware Ensemble Neural Network [PDF]

arXiv
Electronic warfare support (ES) systems intercept adversary radar signals and estimate various types of signal information, including modulation schemes. The accurate and rapid identification of modulation schemes under conditions of very low signal power remains a significant challenge for ES systems. This paper proposes a recognition model based on a
