It is difficult to realize spread spectrum signal acquisition in time transfer system for a receiver operating in dynamic situation. For a receiver that realized by all-digital model, a new acquisition mode using fast Fourier transform algorithm is presented, which estimates the Doppler shift during the PN phase acquisition. The algorithm presented in the paper solves the problem of signal acquisition when the receiver is operated in dynamic situation. The analysis and simulations show that the algorithm is simple in hardware design, efficient and suited for DSP implementation.
