To detect and track the weak target of radar in the clutter environment,PF-TBD algorithm is presented in the clut-ter of Weibull distribution.The algorithm uses a measurement model in the clutter of Weibull distribution based on particle filter and derives likelihood function and particle weights.Simulation results show that PF-TBD algorithm in the clutter of Weibull distribution is stable.
