Eliminating TDOA location ambiguity about HPRF signal based on correlation algorithm

A new method based on correlation algorithm is introduced after analyzing many methods which can solve TDOA location ambiguity of HPRF.Firstly,the different frequency and ambiguous TDOA of HPRF with histogram is computed in this method and TDOA combination is applied based on this method.Finally,by correlation computation to TDOA of different frequency,the real TDOA is acquired.By simulation with computer,TDOA location ambiguity is eliminated by this method,it is proved feasible and effective.
