Compensation Method of Acquisition for High Dynamic DSSS Signal

According to the problem of acquisition error for high dynamic direct sequence spread spectrum signals, a new compensation method is presented to guarantee acquisition phase accuracy of PN code. In this method, the acquisition result of Doppler frequency is used to compensate acquisition phase of PN code based on processing time of acquisition and start-up time of tracking. Analysis and simulation results indicate that the principle of method is correct and the initialize precision for tracking can be ensured especially for high dynamic environment.
