Joint Source Number Detection and DOA Tracking Based on Single Channel Array
Donghai Li · Electronic Information Warfare Technology · 2013
The traditional moving target tracking with single channel array system has low performance.To address this problem,a new method of Direction of Arrival(DOA) tracking for single channel array is proposed.Based on the new array signal data model established by sequential sampling,through the estimation of the expected ariginal signal,a tracking equation is built,then the particle filter is improved with Reversible Jump Markov Chain Monte Carlo(RJMCMC),and finally real time Direction of Arrival and source number is estimated on time.Theoretics analysis and simulation results show that the method presented in this paper can realize joint source number and DOA tracking,and has high tracking precision.Besides,the joint DOA tracking and beamforming could be realized with this method.
