Abstract
Recent research shows that distributed radar has great potential in recognizing and countering deception jamming. In this letter, we investigate how to use deception bistatic range measurements to estimate the target location and deception ranges, and propose a message passing based method for target localization under range deception jamming in distributed MIMO radar. Firstly, the a posteriori distribution of the target location is derived, but its maximization is intractable. Then we represent the joint distribution of the relevant variables as a factor graph model and a highly efficient message passing algorithm is developed, where the target location and deception ranges are estimated iteratively. The Cramer-Rao bound is also derived and numerical simulations are provided to demonstrate the superiority of the proposed method.
