Bearings-only locating algorithm of low-level flying target

Bearings-only locating technique of low-level flying target is very important in military defense. The sensor can only receive bearing information, so it is impossible to obtain the whole state of the target. Based on the hypothesis that the target makes uniform velocity rectilinear motion in three continuous observation periods, a single-stationary sensor single-target locating method is obtained by combining three continuous measurements in time series. The method can be used for nonlinear flying target and simulation results show it is available.
