Abstract
A practically successful method to achieve better estimation results for target trackling with passive measurements has been obtained through the use of a set of modified polar coordinates. This state space consists of the reciprocal of the range, the range rate over range, the range acceleration over range, the bearing angle, the bearing-angle rate, and the bearing acceleration, in two dimensions. The evaluation angle, its rate, and its acceleration are added to the state space in three dimensions. The performance of this modified polar coordinate filter is superior to that of the widely used rectangular Cartesian coordinate-based extended Kalman filter.
