Abstract
AbstractThe interacting multiple model based on a particle filter fails to meet the requirements of real‐time performance when manoeuvring target tracking by radar due to deficiencies in its high calculation complexity. An improved particle filter based on landscape adaptive particle swarm optimization is proposed. This filter adopts the method of updating inertia weight, using not only local information and global information, but also preventing algorithm trapping in a local optimum, so the filter can find the optimal solution with less iteration. Additionally, an improved tracking model is presented. With the help of systematic resampling, the model can figure out the model index of particles. The experimental results prove that the new tracking algorithm not only improves manoeuvring target tracking accuracy, but also decreases computing complexity.
