A new method of phase synchronization for GPS signals based bistatic radar

The phase synchronization is one of the key technologies for bistatic radar. Traditionally, it is used to be synchronized by sampling, analyzing and modifying the phase signal in the windowed FFT spectrum. But, the sync-error can be introduced by sampling the asynchronous signals. In this paper, we use a new method called All-Phase FFT. By the way of All-Phase FFT Analysis, the initial phase can be measured. At first we describe how this new method is developed. Then, we use MATLAB to do some simulations. The simulation result is a comparison of FFT and All-phase FFT. The simulation shows that this method can measure the phase difference precisely for matching the phase synchronization requirements of bistatic radar. All-Phase FFT is a good method that can develop signal processing ability in bistatic radar.
