# espritdoa

Direction of arrival using TLS ESPRIT

## Description

estimates
the directions of arrival, `ang`

= espritdoa(`R`

,`nsig`

)`ang`

, of a set of plane
waves received on a uniform line array (ULA). The estimation employs
the *TLS ESPRIT*, the total least-squares ESPRIT,
algorithm. The input arguments are the estimated spatial covariance
matrix between sensor elements, `R`

, and the number
of arriving signals, `nsig`

. In this syntax, sensor
elements are spaced one-half wavelength apart.

estimates
the directions of arrival with additional options specified by one
or more `ang`

= espritdoa(___,`Name,Value`

)`Name,Value`

pair arguments. This syntax
can use any of the input arguments in the previous syntax.
