An improved localization algorithm of taylor series expansion search target

Due to the real-time positioning, mobility and complexity by environmental goals control, reasonable, efficient determination of the measured time delay difference accuracy has been plagued researchers question. Aiming at this problem, this paper proposes a method to estimate the error signal delay discrimination based on characteristic parameters, using the method of Taylor series expansion location algorithms are search initial and end condition was improved. The experiment proves that this algorithm has high precision, strong robustness etc.
