Accuracy Analysis of Three Aircraft TDOA/FDOA Location
Yulin Wang · Radio Engineering · 2011
The location result is estimated by Newton's iteration from the system of time difference and frequency difference equations.Estimating accuracy and location characteristic are analyzed in theory.Considering to the ambiguity and low accuracy of two aircraft system,the three aircraft system is discussed.The ambiguity is eliminated by any two plane combination and location accuracy is improved by data fusing.It is proved by simulation that three aircraft system is prior to two aircraft system in elimination ambiguity and accuracy.
