Blind Direction-of-Arrival Estimation with Uniform Circular Array in Presence of Mutual Coupling

International Journal of Antennas and Propagation, 2016
A blind direction-of-arrival (DOA) estimation algorithm based on the estimation of signal parameters via rotational invariance techniques (ESPRIT) is proposed for a uniform circular array (UCA) when strong electromagnetic mutual coupling is present ...

An Efficient ISAR Imaging of Targets with Complex Motions Based on a Quasi-Time-Frequency Analysis Bilinear Coherent Algorithm

Sensors, 2018
The inverse synthetic aperture radar (ISAR) imaging for targets with complex motions has always been a challenging task due to the time-varying Doppler parameter, especially at the low signal-to-noise ratio (SNR) condition.

Educational Track, Networks and Labor Market Outcomes [PDF]

SSRN Electronic Journal, 2003
Does the educational track (technical or professional, as opposed to general) provide individuals with networks that are useful in the labor market? And how do these networks help? In this paper, we consider the effect of the educational track on the means by which individuals find employment, the time it takes to find their first stable job and their ...
