Ambiguity Function and Frame-Theoretic Properties of Periodic Zero-Autocorrelation Waveforms
Publication Year: 2007, Page(s):6 - 20
Cited by: Papers (22)Periodic constant-amplitude zero-autocorrelation (CAZAC) waveforms u are analyzed in terms of the discrete periodic ambiguity function A <sub>u</sub>. Elementary number-theoretic considerations illustrate that peaks in A<sub>u</sub> are not stable under small perturbations in its domain. Further, it is proved that the analysis of vector-valued CAZAC waveforms depends on met... View full abstract»

The focus is on the temporal aspects of the waveform with the spatial aspects to be described in a future paper. The assumptions involved in modeling the clutter/reverberation return are crucial to the development of the optimal detector and its consequent o... View full abstract»

Adaptive Waveform Design for Improved Detection of Low-RCS Targets in Heavy Sea Clutter
Publication Year: 2007, Page(s):56 - 66
Cited by: Papers (53)The dynamic adaptation of waveforms for transmission by active radar has been facilitated by the availability of waveform-agile sensors. In this paper, we propose a method to employ waveform agility to improve the detection of low radar-cross section (RCS) targets on the ocean surface that present low signal-to-clutter ratios due to high sea states and low grazing angles. Employing the expectation... View full abstract»

Adaptive Games for Agile Spectrum Access Based on Extended Kalman Filtering
Publication Year: 2007, Page(s):79 - 90
Cited by: Papers (9)For dynamic spectrum allocation (DSA), distributed game has emerged as an attractive approach that enhances radio spectrum utilization efficiency at scalable complexity in network size. Cognitive radios act as game players to judiciously decide their transmission power spectrum density (TPSD) based on channel state information (CSI), which is generally estimated independently from the DSA games an...

Transmit-Signal Design and Processing Strategies for Sonar Target Phase Measurement
Publication Year: 2007, Page(s):91 - 104
Cited by: Papers (16)The majority of active sonar systems detect and classify a target based on the amplitude of the received echo strength or the induced Doppler shift. However, additional classification information is available from the phase shift introduced by some targets as a result of the acoustic boundary conditions. For example, reverberation returns from the sea surface and from the swimbladders of various f... View full abstract»

Adaptive Waveform Design and Sequential Hypothesis Testing for Target Recognition With Active Sensors
Publication Year: 2007, Page(s):105 - 113
Cited by: Papers (149)Cognitive radar is a recently proposed approach in which a radar system may adaptively and intelligently interrogate a propagation channel using all available knowledge including previous measurements, task priorities, and external databases. A distinguishing characteristic of cognitive radar is that it operates in a closed loop, which enables constant optimization in response to its changing unde... View full abstract»

Cited by: Papers (8)By exploiting the reflective and refractive nature of high-frequency (HF) radiowave propagation through the ionosphere or the conducting sea surface, over-the-horizon radar (OTHR) systems perform wide-area surveillance at long range well beyond the limit of the horizon of conventional line-of-sight (LOS) radars. Improved characterizations of the targets can be achieved by using multiple OTHRs oper... View full abstract»

Cited by: Papers (94)We consider the problem of minimax robust waveform design for multiple-input multiple-output (MIMO) radar based on mutual information (MI) and minimum mean-square error (MMSE) estimation for target identification and classification. Recognizing that a single, precise characterization of target power spectral density (PSD) is rare in practice, we assume the PSD lies in an uncertainty class of spect... View full abstract»
