In the spectrum-congested environment, weak target obscuration can be addressed by simultaneously shaping ambiguity function and waveform spectrum based on cognitive radar a priori information. this paper, we investigate joint design to suppress slow-time (STAF) disturbance power overlapping frequency band energy. Thus, novel criterion involving minimizing interested range-Doppler blocks of STA...

in recent years, wavelet packet modulation ofdm (wpm-ofdm) signals have been introduced for radar applications. these signals have important properties such as inherent high range resolution and high resistance of radar system against jamming reception. this paper investigates the problem of designing these family of signals according to the following criteria: constrained maximization of the d...

Data from previous neuroimaging studies exploring neural activity associated with uncertainty suggest varying levels of activation associated with changing degrees of uncertainty in neural regions that mediate choice behavior. The present study used a novel task that parametrically controlled the amount of information hidden from the subject; levels of uncertainty ranged from full ambiguity (no...

Appeared in: P. Dekker (Ed.) Proceedings of the 12th Amsterdam Colloquium (AC’99). Institute for Logic, Language and Computation, 1999, pages 43–48. This paper investigates the formal pragmatics of ambiguous expressions by modeling ambiguity in a multi-agent system. Such a framework allows us to give a more refined notion of the kind of information that is conveyed by ambiguous expressions. We ...
