Abstract

Considering the huge calculation in estimation of TDOA/FDOA using conventional CAF algorithmic, a fast algorithm based on coherent accumulative of a approximate calculation of short-time CAF is proposed. Feasibility and performance of the fast algorithm is analyzed. Simulation analysis of conventional and fast CAF algorithmic under the same condition is performed. The simulation results show the effectiveness of the new algorithmic, and it can cut down time consumption around 90%.
