Cognitive processing for nonlinear radar
SPIE Proceedings, 2013An increasingly cluttered electromagnetic environment (EME) is a growing problem for radar systems. This problem is becoming critical as the available frequency spectrum shrinks due to growing wireless communication device usage and changing regulations.

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

USRP based cognitive radar testbed
2017 IEEE Radar Conference (RadarConf), 2017Cognitive radar is a relatively new field of research and the existence of low cost experimental testbeds is limited. This work will show the development of a low cost experimental testbed for experimental validation of cognitive radar algorithms. The testbed is based on USRP's, which is a low cost software defined radio developed by Ettus.

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 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.

Cognition in radar target tracking
2017This chapter has been devoted to the design of a tracker exploiting cognition at multiple levels. Specifically, environmental maps and characteristics of the targets, available in the dynamic database possibly learned from the feedback channel, have been used to gain improved tracking performance in a multiple targets scenario exploiting measurements ...

Cognitive over-the-horizon radar
Proceedings of 2011 IEEE CIE International Conference on Radar, 2011Combined the characteristics of skywave over-the-horizon radar with the concept of cognitive radar, cognitive over-the-horizon radar (COTHR) becomes an important development approach of over-the-horizon radars. Integrating multitasking requirements with real-time dynamically sensing to propagation media--the ionosphere, COTHR assigns intelligently the ...

Potential pitfalls of cognitive radars
2014 IEEE Radar Conference, 2014Cognitive radar architectures offer the community many potential benefits including the potential of improving sensor system performance while simultaneously reducing the cost of future radar systems. However, as with many new technologies, it is important that, in addition to understanding its benefits, the developers of such advanced cognitive radar ...
