Rational layout of laser fake targets is a key link in the process of successful implementation of laser angle deception jamming.Under the condition of complex terrain,false target setting is often affected by environment factors,such as surface features,buildings and vehicles.There are many forbidden areas,which will cause that human decision-making is difficult to form the best layout scheme quickly.Through analyzing the principles of false target deployment,fake target layout scheme in complex terrain is optimized using particle swarm algorithm,and the feasibility and adaptability of the algorithm are verified according to three kinds of application scenarios.
