Direct tracking of noncircular sources for multiple arrays via improved unscented particle filter method

Direct tracking problem of moving noncircular sources for multiple arrays is investigated in this study. Here, we propose an improved unscented particle filter (I-UPF) direct method, which combines system proportional symmetry and Markov Chain Monte Carlo (MCMC) algorithm. Noncircular can extend the dimension matrix, accuracy improved. This method uses to receive sources. Firstly, set up a model through consecutive time Doppler information. Subsequently, based on algorithm, proposed improve reduce computational complexity. Simulation results show that algorithm has enhanced than extended Kalman filter, two-step method.
