摘要

In view of the acquisition problem for high dynamic direct sequence spread signals, a new method of acquisition is presented. The method completes signal acquisition by twice frequency domain search based on fast Fourier transform. In this method, the whole range of Doppler frequency for signals is searched in addition with a second round verification. Analysis and simulation results indicate that the principle of the method is correct and it has better acquisition accuracy and great performance especially for higher dynamic environment.
