Triple extended coprime array for single‐snapshot DoA estimation

Electronics Letters
The direction‐of‐arrival (DoA) estimation methods based on coprime array (CA) largely rely on having a sufficient number of snapshots. However, under single‐snapshot conditions typical of vehicle‐mounted imaging radar, CA‐based DoA estimation often ...

COPRIME ARRAYS WITH ENHANCED DEGREES OF FREEDOM

Anadolu University Journal of Science and Technology-A Applied Sciences and Engineering, 2018
Coprime array geometries provide robust performance for direction-of-arrival estimation problem with more sources than sensor elements. In previous works it is shown that K source directions can be resolved using only 2M + N -1 sensor elements where K is less than or equal to MN.

Prime-coprime-series and the logarithm of a complex exponential

, 2020
This paper studies the logic of primes through prime-coprime-series. These series may be expressed with a general formula which, transformed, shows the link with Euler’s product formula in its regression-equation.
