MIMO Target Location Estimation Method for Distributed MIMO Radar using Extended Ellipsoids Fitting

摘要

Disclosed is a method for estimating a target position. The method for estimating a target position comprises the steps of: (a) modeling ellipsoids having a bistatic range, which is a distance value from transmitters to receivers via a target, as a long axis, and having a focus on three-dimensional coordinate values of the transmitters and receivers, and constructing ellipsoid equations for the modelled ellipsoids; (b) adding all the ellipsoid equations for each of the constructed ellipsoids to construct a quadratic equation whose variable is an altitude value of the target; and (c) calculating an altitude value of the target from the constructed quadratic equation.
