Effect of high repetition frequency on laser decoding recognition process

To estimate the impact of high repetition frequency jamming on laser decoding,the normalized cross-correlation function method was adopted. The effect of high repetition frequency jamming on precise frequency code during the distinguishing process of decoding was quantified under two circumstances. One was that only the jammed signal entered into the time-gate, the other was that the jammed signal entered into the time-gate at a certain time before the guiding signal. Experimental results show that the jamming effects are different for different jamming ferquency and the jamming effect is the best when the high frequency comes to 100kHz. The simulation of the effect of different factors provides the basis to analyze the jamming effect of high frequency signal.
