Integrated Track-and-Detect Method Based on Recursive Bayesian
Peng Yingning · Journal of Astronautics · 2011
In radar systems,detecting and tracking of targets with small RCS and maneuvering targets is a difficult point.In this paper an integrated method named TD is put forward to improve detecting and tracking performance for these targets,which is based on recursive Bayesian theory.Furthermore,a new approach for improving the recursive Bayesian method is described to handle these targets.This approach utilizes a priori information or on-line estimation of target velocity to update the moving model's parameters.Simulation result and comparison with other approaches are presented.On condition that the mean signal to noise ratio of maneuvering target is 6dB,this approach makes the result that the false-alarm probability is 10-3 while the detection probability is 0.9.
