FDOA A Method for High Precise FDOA Estimation using the Phase Difference and System thereby

摘要

According to the present invention, a high precise FDOA estimation method using the phase deference of a high precise FDOA estimation system includes a signal collecting step by a plurality of spaced receivers (1) in which signal sampling, collection and detection are performed on the emitted pulse column (4) of a signal source (3), a high precise phase measurement step of the receivers (1) in which the instantaneous phase measurement of removing the influence of instantaneous phase measurement time error on pulse signals collected and detected after the signal sampling is performed, and an FDOA measurement step of a central processor (2) which calculates FDOA between the plurality of receivers (1) in the result of the instantaneous phase measurement. So, it is possible to realize a characteristic in which a measurement error is minimized for each of the plurality of receivers (1).
