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

摘要

A method for estimating a target position is disclosed. The method for estimating the target position is (a) an ellipsoid having a bistatic range, which is a distance value from transmitters to receivers via a target, as a long axis, and a three-dimensional coordinate value of the transmitters and receivers as a focus. Modeling them, and constructing an ellipsoid equation for the modeled ellipsoids, (b) adding all of the ellipsoid equations for each of the configured ellipsoids to construct a quadratic equation with the altitude value of the target as a variable, and (c) calculating the altitude value of the target from the constructed quadratic equation Steps.
