A new method for initial code acquisition in spread spectrum systems is compared in terms of the resulting mean acquisition time with the single dwell acquisition scheme in the case where a non uniform a priori information is provided and advanced searching strategies are utilised. The novel scheme employs a fast preliminary search of the ambiguity area. The results of the fast search are used as a priori information for the final search. The probability of false ranking P-fr is defined as a measure of thr reliability of the a priori information provided by the fast preliminary search. A similar idea, used to perform a spatial search for a lost satellite in a region of the sky, has been described in . A detailed analysis of the FPS system is presented in .
