A multiple FPGAs cascade method in countermeasure of laser high repetition frequency jamming

This paper analyses the principle and effect of active laser high repetition frequency jamming in the semi-active laser guidance. According to existing decoding methods for active laser high repetition frequency jamming, a cascade way of multiple FPGAs is proposed and its principle and rule are introduced, especially, the cascade and codec synchronization methods are involved, providing a new thought for confronting the laser high repetition frequency jamming. At last, future trend of laser high repetition frequency jamming countermeasure is summarized.
