摘要

A TDOA and FDOA estimation method according to an embodiment of the present invention includes a first signal that is a portion received through a first receiver during a predetermined reception time from a pulse-shaped detection target signal emitted from a target, A first step of acquiring a second signal, which is a part received during the reception time, through a second receiver which is spaced apart from the first receiver by a predetermined distance from the first receiver, And a second step of estimating TDOA and FDOA of the detection target signal with respect to the second receiver, wherein the second step includes the steps of: Determining a magnitude between a period and a value corresponding to twice the maximum TDOA which is a maximum value of the TDOA that can be calculated based on the spacing distance; The maximum value of the FDOA, which is the maximum value of the value that the FDOA can have, which is calculated based on the predetermined maximum sensing speed, which is the maximum speed that the target can have, when the pulse period is less than twice the maximum TDOA Estimating the FDOA prior to the estimation of the TDOA within a range in which the TDOA is not large and if the pulse period is more than twice the maximum TDOA, Estimating prior to the FDOA estimation.
