New Algorithms in Cognitive Radar
2018 11th International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI), 2018Cognitive radar is a kind of new concept radar system which can solve the target detection problem under the complex environment. It can highly improve the radar performance through knowledge aided adaptive processing. In this paper, aimed at the crucial problems and the bottleneck which the traditional radar faces to, the concept and the configuration

Cognitive Beamforming in Radar Bands
IEEE Transactions on Communications, 2018We investigate the problem of beamformer design for communications systems coexisting with legacy radar systems with mechanically rotating antennas. Based on measurement campaign findings that support the assumption of fast decoherence for the radar-to-base station interference within a radar rotation, as well as the assumption of very strong ...

Cognitive Radar for Classification
IEEE Aerospace and Electronic Systems Magazine, 2019The article presents the cognitive radar architecture of Fraunhofer FHR based on a three-layer model of human cognitive performance. The approach is illustrated using examples for non-cooperative target identification and classification. On the skill based layer, a target-matched waveform design is presented and experimental results are shown.

2010 IEEE Radar Conference, 2010
For the first time ever, this paper presents the design and implementation of a next-generation of tracking radar systems: the cognitive tracking radar (CTR). At the heart of the CTR, we have a cognitive waveform-selection (CWS) algorithm that can optimally pick the transmit waveform from a prescribed library, in response to information fed back from ...

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 ...

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 ...

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 ...
