Jointly tracking the time-varying parameters of array incident signals is the chief problem that our troops efficiently carry out electronic defense and offense in modern electronic war(EW).Aiming at the problem that the methods to estimate time-invariant parameters don't adapt themselves to the situation to track time-varying parameters

this paper has probed into the method to jointly track time-varying parameters of array signals based on the plane rotation(Givens rotation).The computer simulation results proved the effectivity of proposed method.
