Abstract:To solve the problem of low accuracy for multiple targets tracking in case of low SNR(signal noise ratio), a MIMO radar DOA(direction of arrival) tracking method based on SDE model is proposed in this paper to correct error of tracking model. The stochastic differential equation and the particle filter based on Markov Chain Monte Carlo (MCMC) are used for modeling and continuous reasoning for the multiple targets. The effectiveness of this method is verified by the simulation results, the tracking accuracy of motion multiple targets can be improved by more than 20% in case of low SNR.
