Convergence issues of taylor series method in determining unknown target location using hyperbolic multilateration

Modern Electronic Warfare systems need to provide real time location information in a consistent, unambiguous and timely manner. The time difference of arrival (TDOA) techniques used for location determination make use of the method of hyperbolic multilateration. One technique which is widely used for solving non linear hyperbolic equations is the Taylor Series method. This paper discusses the convergence issues the method faces and analyses the possible effect of variations in receiver distribution on coPnvergence of the solution.
