Monte Carlo Simulation on Interference Resistance of Pulsed Laser Fuze Using Pseudorandom Code

The Monte Carlo simulation focuses on the interference resistance of pulsed laser fuze based on pseudorandom code. Considering the self-coherence of the pseudorandom code,a distance model was established to analyze the interference resistance of pulsed laser fuze based on pseudorandom code. And in order to compute the probability of detection and false alarm separately,a statistic numerical simulation model based on Monte Carlo algorithm was established for laser fuze based on periodic pulse as well as that based on pseudorandom code. The simulation shows the pulsed laser fuze based on pseudorandom code has a high resistance to interference.
