Cognition, a basic concept in psychology, is the set of a human's inner mental activities and processes related to knowledge. Actually it is possible to introduce cognition into engineering systems to construct intelligent systems with human cognitive functions. Cognitive radar is such a successful case that improves the working performance in complex(More)
Infrared detection is significant in many fields, and sometimes infrared images are used to cover the shortcomings of visible images. Then image fusion between visible and infrared image is important in practical use. In this paper, we introduce Curvelet transform and its implementation to decompose images to different resolutions, and standard fusion rules(More)
Quantum radar is a remote sensor that exploits quantum phenomena to perceive target in the distance and receive its state information. In this article, the concept and principle of quantum radar are introduced in detail, including interferometrie quantum radar, quantum ladar and quantum illumination radar. And it is proved in theory that quantum radar can(More)
This paper presents a phase compensation method for high dynamic target echoes, of which the echo phase is not linear but polynomial. Restricted by minimum entropy criterion, coefficients of each order of the echo phase are estimated and utilized to compensate the nonlinearity of the phase. Then the Doppler frequency estimation with higher accuracy can be(More)
