The Geometry of Signal Detection with Applications to Radar Signal Processing [PDF]

open access: yesEntropy, 2016
The problem of hypothesis testing in the Neyman–Pearson formulation is considered from a geometric viewpoint. In particular, a concise geometric interpretation of deterministic and random signal detection in the philosophy of information geometry is presented.

Coprime sampling for nonstationary signal in radar signal processing [PDF]

open access: yesEURASIP Journal on Wireless Communications and Networking, 2013
Estimating the spectrogram of non-stationary signal relates to many important applications in radar signal processing. In recent years, coprime sampling and array attract attention for their potential of sparse sensing with derivative to estimate autocorrelation coefficients with all lags, which could in turn calculate the power spectrum density.
