Paper Abstract

The partial correlation acquisition for medium-long PN code is a fast acquisition method under high dynamic circumstance. This article analyzes the performance of partial correlation method based on FFT to estimate the Doppler frequency in the case of Gaussian noise environment, In this paper we take GPS civil signal L5 which has length of 10230 chips and a transmission rate of 10.23 MHz for example, deduce the formulas of the probability of false alarm and probability of detection of this method and give the best subsection method at different Doppler frequency range through simulation and theoretical analysis, with the simulation results in accord with theoretical analysis.
