Aimed at the problem that the algorithm of asynchronous sensors bias estimation cannot adapt to the maneuver targets, a novel algorithm based on the interpolation was researched. Firstly, the measurement was changed into synchronization data by using the time registration method. Then, the pseudo measurement equation could be obtained according to the time registration results. Be different from other algorithms of which the pseudo measurement, independent of target state, is obtained by getting a adding coefficient according to the target state vector and time of arrival (TOA), the depseudo measurement deigned has no relationship to the target state vector. Moreover, the derivation of the pseudo measurement according to the time registration results is also independent of the movement of target. So, the problem of asynchronous sensors bias estimation with maneuver targets can be solved by the algorithm proposed. The results of simulation show that the sensor bias could be exactly estimated when the target takes a snake maneuver.
