Method for Jitter Signal Detection of GPS Basing on Non-Sequential Sampling

Because of the high frequency of GPS signals, it is hard to maintain good real-time performance in jitter signals detection. This paper introduced the character of non-sequential sampling and the principle for detection of instantaneous jitter signal at first, and then presented a method for jitter signal detection of GPS based on non-sequential sampling. The software procedure and hardware circuit is given subsequently. Experiments show that this method can effectively determine the accurate time at which the jitter interference occur, and the realtime performance of the method is satisfactory. Basing on this method we can realize the position of jamming sources by directivity synthesis of antenna array in future work. With the development of satellite systems, the applications of this method are becoming more and more widespread.
