Algorithm to obtain arbitrary coarrays using synthetic aperture techniques

In this work we present a new algorithm, based on the polynomial division, that allows to obtain a desired coarray with arbitrary shape on a lineal array, using a synthetic aperture configuration with a finite number of subapertures of equal length. With this fast and simple algorithm, the wanted co...

Description
Summary:In this work we present a new algorithm, based on the polynomial division, that allows to obtain a desired coarray with arbitrary shape on a lineal array, using a synthetic aperture configuration with a finite number of subapertures of equal length. With this fast and simple algorithm, the wanted coarray is decomposed into a set of subapertures whose length is fixed by the requirements and resources of the system. The result is a set of coefficients that should be applied on the subapertures to synthesize the desired coarray, and consequently, the beam pattern wanted.
