Spectrally Limited Periodic Waveforms for HF OTHR Applications
Yuri Abramovich, Dan Dickey, Victor Abramovich
The problem of a constant modulus (CM) continuous wave (CW) waveform design with the thumb-tack ambiguity function that meets the NTIA RSEC requirements is addressed. The ad-hoc an…
Robust Covariance Estimation under Imperfect Constraints using an Expected Likelihood Approach
Bosung Kang, Vishal Monga, Muralidhar Rangaswamy +1
We address the problem of structured covariance matrix estimation for radar space-time adaptive processing (STAP). A priori knowledge of the interference environment has been explo…
Bounds for maximum likelihood regular and non-regular DoA estimation in -distributed noise
Yuri Abramovich, Olivier Besson, Ben Johnson
We consider the problem of estimating the direction of arrival of a signal embedded in -distributed noise, when secondary data which contains noise only are assumed to be availa…
On the Fisher information matrix for multivariate elliptically contoured distributions
Olivier Besson, Yuri I. Abramovich
The Slepian-Bangs formula provides a very convenient way to compute the Fisher information matrix (FIM) for Gaussian distributed data. The aim of this letter is to extend it to a l…
