In this paper, the characteristic of ultra-wideband (UWB) arrays is analyzed in space-time domain and a method of direction-of-arrival (DOA) estimation for impulse signal is introduced. This method borrows ideas from signal's cycle stationary characteristic in communication system. By decomposing the output signals' correlation matrix of the UWB arrays, the DOA information is obtained. Simulation result shows that if the cycle frequency isn't high, this method is valid.
