For low accuracy of Taylor-series location,a joint location method,using time-difference-of-arrival(TDOA) and frequency-difference-of-arrival(FDOA) based on probability location algorithm,is presented.Nonlinear equations are proposed in this method,then nonlinear equations are changed into one-order linear equations based on probability theory,the estimated position of the target is achieved according to the linear equations.It can be proved by computer simulations that this method has better accuracy than Taylor-series method.
