Abstract: An approach for identification of dense modes' parameters of flexible space structures is studied.Based on wavelet transformation of the system impulse response,when the selected wavelet's analysis frequency is enough high,the closely spaced low frequencies of flexible space structures can be accurately separated and mode parameters be estimated.Simulation results are given to demonstrate the effectiveness of the proposed approach.
