METHOD FOR ASSUMING DISTANCE BETWEEN TRANSMITTER AND RECEIVER IN SYSMTEM FOR TRANSMITTING AND RECEIVING CHIRP SIGNAL AND THE SYSTEM THEREOF

摘要

PURPOSE: A distance presuming method and a system thereof for improving system performance in a chirp signal trnasceiving system are provided to reduce operation quantity by reducing the size of a sub matrix. CONSTITUTION: A dechirping processor(24) performs a dechirping process abut a sub-chirp signal. The dechirping processor samples the sub-chirp signal into the dechirping signal. An SVD(Singular Value Decomposition) processor(26) performs an SVD process about a matrix. The SVD processor generates a first sub matrix and a second sub matrix. A delay value estimating unit(28) presumes delay value. A distance presuming unit(30) determines distance from a transmitter.
