A cognitive approach for radar receiver adaptation

2016 IEEE 2nd International Forum on Research and Technologies for Society and Industry Leveraging a better tomorrow (RTSI), 2016
Cognitive radar is a new paradigm to conceive the next radar generation characterized by unique and amazing features inspired to mental abilities and processes related to knowledge. It goes beyond the usual extraction of information from the measurements and requires the radar to get intelligence.

Modeling and Simulation of Cognitive Radars

2020 IEEE Radar Conference (RadarConf20), 2020
Cognitive radar has emerged as key enabling technology to meet the demands of ever increasingly complex and congested radio frequency (RF) operating environments. The generally non-stationary, heterogeneous, and time-varying nature of the modern RF environment all but precludes the use of traditional adaptive processing methods that require the ...

Cognitive Nonlinear Radar

2013
Abstract : In this report, a unique cognitive nonlinear radar (CNR) is introduced. Research and development efforts for the CNR are currently funded by the U.S. Army Research Laboratory (ARL). The CNR adapts to (1) an increasingly cluttered electromagnetic (EM) environment, a growing problem for ground-based and airborne radar systems; (2) multiple ...

Spectrum estimation for cognitive radar

2015 European Radar Conference (EuRAD), 2015
One of the critical functions of a cognitive radar is to examine a large frequency spectrum in real time, in order to detect the presence of narrowband emitters, which radiate on the same frequencies as a wideband radar. The final goal of spectrum monitoring is to recognize which frequency channels of the radar spectrum are occupied over a certain time

Practical Aspects of Cognitive Radar

2020 IEEE Radar Conference (RadarConf20), 2020
In this paper we examine some of the practical aspects of implementing cognitive radar (CR) techniques onto software defined radar (SDRadar) platforms. These aspects include: 1) the response time (RT) of algorithms and components to determine latency bottlenecks, 2) autonomous regulation of the perception-action cycle (PAC) to determine “how fast the ...

Basic understanding of cognitive radar

2016 IEEE ANDESCON, 2016
It is the purpose of this article to discuss about the definitions of Artificial Intelligence, Cognitive System and Cognitive Radar. Moreover, the concepts of Cognitive Radar will be described in this paper as their principal components, the technologies required to support these and Cognitive Radar Network.

Cognitive tracking in IEEE 802.22 Symbiotic Radars

2016 24th European Signal Processing Conference (EUSIPCO), 2016
This paper focuses on a Symbiotic Radar, that is a Passive Radar which is an integral part of a communication network. The Symbiotic Radar exploits the signals of opportunity emitted by the Base Station (BS) and the Customer Premise Equipments (CPE) of an IEEE 802.22 WRAN.

Compressed spectrum Sensing in Cognitive Radar systems

2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014
Compressed Sensing is a new signal processing methodology that allows to reconstruct sparse signals using a relatively small number of samples in the form of random projections. These samples are collected at a much lower rate than Nyquist rate. This paper focuses on the application of Compressed Sensing in Cognitive Radar systems that use wide ...

Toward the Development of Radar Scene Analyzer for Cognitive Radar

IEEE Journal of Oceanic Engineering, 2010
In this paper, we propose a target signature search algorithm to address the radar scene analyzer in explicit terms for cognitive radar reception. A cognitive radar receiver encompasses two main blocks: the radar scene analyzer (RSA) and the Bayesian target tracker (BTT).

Cognitive radar management

2017
Cognitive radar is a radar system that acquires knowledge and understanding of its operating environment through online estimation, reasoning and learning or from databases comprising context information. Cognitive radar then exploits this acquired knowledge and understanding to enhance information extraction, data processing and radar management.
