Signals are restored by multi-period sampling to overcome the time-delay of sub-sampling high frequency signals and reduce the complexity of estimation.These signals are used for the time-delay estimation with noise interference.The performance analysis and Doppler error correction are given.Simulations prove the validity of this method.

Key words: sub sampling;correlation method;time delay estimation;doppler error correction
