Cognitive Radars: A Reality? [PDF]

open access: yesarXiv, 2018
This paper describes some key ideas and applications of cognitive radars, highlighting the limits and the path forward. Cognitive radars are systems based on the perception-action cycle of cognition that sense the environment, learn from it relevant information about the target and the background, then adapt the radar sensor to optimally satisfy the ...

Taming and Leveraging Interference in Mobile Radar Networks [PDF]

open access: yesarXiv, 2020
Mobile radar networks, such as autonomous driving systems, are subject to the severe challenge of mutual interference. Despite the inborn interference-proof capability in frequency modulation continuous waveform (FMCW) radar, interference management is necessary for dense radar networks.

Preliminary tests of an airborne meteorological pulse Doppler radar

open access: yesGeophysical Research Letters, 1980
An X‐band Doppler radar in the tail of a WP‐3D research aircraft has been used to conduct tests which demonstrate that technology developed for ground‐based Doppler radar can be applied to an airborne system. The Doppler spectra of meteorological targets and chaff have been measured with the airborne radar, and these measurements compared favorably ...

Doppler Ambiguity Resolution Based on Random Sparse Probing Pulses

open access: yesJournal of Electrical and Computer Engineering, 2015
A novel method for solving Doppler ambiguous problem based on compressed sensing (CS) theory is proposed in this paper. A pulse train with the random and sparse transmitting time is transmitted.

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

open access: yesarXiv
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.

Probing of Atmospheric Motion by Airborne Pulse-Doppler Radar Techniques

open access: yes, 1971
The paper discusses the use of airborne pulse-Doppler techniques for the sensing of particle motion inside convective storms. A downward-looking beam method providing observations of particle vertical velocity distributed in a vertical plane generated by
