With the extensive use of satellite communications, satellite incidents of interference have been increasing. Satellite interference localization has become a new and important content of the current anti-jamming satellite communications system, while the key to the satellite interference localization accuracy is the parameter estimation of Time Difference of Arrival (TDOA) and Frequency Difference of Arrival (FDOA) of the wireless signal. At present, the most commonly used satellite interference localization method is the cross-ambiguity function (CAF) based on the correlation principle. Due to the computing intensity and time consuming searching process of the CAF algorithms, it can not meet the need of quick and accurate satellite interference localization. Thus, the searching of faster and more accurate localization parameter estimation algorithm has become the core of the interference positioning problem.Based on the background of the double satellite localization system, the thes...更多is studied a number of issues of satellite interference localization parameter estimation from TDOA parameter estimation, FDOA parameter estimation and TDOA/FDOA joint parameter estimation respectively.In TDOA parameter estimation, Generalized cross correlation method and Bispectrum methods are classical estimation methods.
