Abstract

To estimate the effect of high repetition frequency laser jamming on laser seeker’s distinguishing and locking stage for decoding process, two models are built to quantitatively study the jamming effect under the different coding systems, one is normalized cross-correlation function model, the other is jamming efficiency model. The simulation result indicates that, at the stage of code distinguishing, the jamming frequency is a dominant factor in affecting the jamming effect; The effect of high repetition frequency laser jamming seeker under the different coding system is different; The greater the seeker sampling interval is, the better the effect is. At the stage of code locking, the leading time of high repetition frequency laser to guidance signal is an important factor in affecting the jamming efficiency; The higher the jamming frequency and the wider the time gate’s width is, the higher the average efficiency of interference is . High repetition frequency laser can completely jam the decoding process of the two stages when the laser frequency is high enough.
