Paper Abstract

Compare with width antenna beam system, a narrow beam system need a faster angle catching method. In this paper, three kinds of methods are introduced: the first one is the delay autocorrelation method; the second one is cross correlation method; the last one is cycle spectrum correlation method. All these three methods need no data demodulation, so they can output angle value quickly. They have different advantages and disadvantages, and are used in different condition. Delay autocorrelation method is fit for mono-channel and mono-pulse angle tracking system. The received signal pass a delayer, then correlate with itself. A notable advantage of the method is that it has a very simple structure. But its performance is not very good when SNR is very low. Cross correlation method is only fit for double-channel and mono-pulse angle tracking system .But it can improve the output accuracy, reduce the influence of noise. Spectrum correlation method has perfect performance. But it needs much more resource. This paper introduces theories and performance of these three methods, especially in high dynamic and low SNR condition .Then it points out how to select a method in different condition according to their characters.
