Direction of Arrival Estimation Using Two Hydrophones: Frequency Diversity Technique for Passive Sonar

Sensors, 2019
The traditional passive azimuth estimation algorithm using two hydrophones, such as cross-correlation time-delay estimation and cross-spectral phase estimation, requires a high signal-to-noise ratio (SNR) to ensure the clarity of the estimated target ...

A doublet of cosmic-ray events with primary energies >10^20 eV

, 2012
The Telescope Array Collaboration has observed a cosmic-ray event with estimated primary energy of 1.38*10^20 eV whose arrival direction coincides (see arxiv:1205.5984), given the angular resolution of 1.5 deg, with that of an event with estimated ...

HOS-based direction of arrival estimation

Electronics Letters, 1994
A new technique for estimating the direction of arrival of multiple non-Gaussian signals using higher order statistics is reported. A set of new algorithms based on a new class of performance criteria related to the bispectral power of the array data is presented.

Arrival direction distribution of cosmic rays of energy 10 (18) eV [PDF]

The Haverah Park air-shower experiment recorded over 8500 events with primary energy 10 to the 18th power eV between 1963 and 1983. An analysis of these events for anisotropies in celestial and galactic coordinates is reported.

Multiple Parameter Estimation With Quantized Channel Output

, 2010
We present a general problem formulation for optimal parameter estimation based on quantized observations, with application to antenna array communication and processing (channel estimation, time-of-arrival (TOA) and direction-of-arrival (DOA) estimation)
