%X Based of known waveform, known period and concentrated energy of distance signal in TACAN system , an efficient time delay estimation algorithm for multipath signal of distance signal is presented in this paper, according to the former frequency spectral division algorithm. Firstly, the crosspower spectrum function is divided by frequency spectrum of referenced signal,. And the energy of out-of-band noise is not enhanced via using compensation factor. Then, the useful signal is restored from receiving signal via IFFT. Finally, the delay is estimated from restored signal. Its effectiveness is verified with the simulation results.
