# tdoaposest

## Syntax

## Description

estimates the position `tgtposest`

= tdoaposest(`tdoaest`

,`tdoavar`

,`anchorpos`

)`tgtposest`

of a target using signals at multiple
anchors with known positions `anchorpos`

. Position is based on
time-difference of arrival (TDOA) measurements between the target and anchors.
`tdoavar`

represents the variance of the time-difference of arrival
measurements.
