Spectrum crowding and Cognitive Radar
2010 2nd International Workshop on Cognitive Information Processing, 2010The ever increasing demand on remote sensing capabilities directly conflicts with the accelerating loss of spectrum allocation. Increased spectral awareness and waveform diversity can be applied to this problem through cognitive processing and control of modern radar. This paper motivates the development of essential technology for this purpose.

Adaptive radar: evolution to cognitive radar
IEEE International Symposium on Phased Array Systems and Technology, 2003., 2004Summary form only given. Adaptive signal processing is considered to be one of the enabling technologies that will become increasingly dominant in the twenty-first century. Most important, it is well suited for use in the design of phased array radar systems, given the flexibility that such a radar system offers.

2011 International Conference on Electromagnetics in Advanced Applications, 2011
Cognition means ‘kowning’ and is the process by which we know about the world‥ In human beings this is extremely complicated and although much is understood there is much more to be learnt. However, humans and perhaps more pertinently for radar systems, echo locating mammals are able to sense and interact with their environment in sophisticated ways ...

Fourth IEEE Workshop on Sensor Array and Multichannel Processing, 2006., 2006
This paper describes the use of cognitive radar networks for the reliable surveillance of an environment where the likelihood of the presence of uncooperative targets is high. Despite the limited effectiveness of amplitude as a radar discriminant, through the clever use of detection through tracking, the detection performance of the noncoherent radar ...

Optimal waveform design for cognitive radar
2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008A key component of a cognitive radar system is the method by which the transmitted waveform is adapted in response to information regarding the radar environment. The goal of such adaptation methods is to provide a flexible framework that can synthesize waveforms that provide different tradeoffs between a variety of performance objectives, and can do ...

Recent trends and findings in cognitive radar
2015 IEEE 6th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2015We provide an overview of recent advances that have come about in the area of cognitive radar over the past decade. The area of cognitive radar involves closed loop radar operation to overcome the challenges imposed by harsh environments, difficult targets, and a rapidly shrinking spectrum.

Compressed spectrum Sensing in Cognitive Radar systems
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014Compressed 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 ...

Practical Aspects of Cognitive Radar
2020 IEEE Radar Conference (RadarConf20), 2020In 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 ...

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), 2015One 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
