Information geometry is a set of system info originated from the study on the geometry properties of statistical manifold, which offers one kind of new thinking and method to the radar signal processing problems. A new kind of view to radar target detection problem is given based on information geometry theory in this article,simultaneously,information geometry method to radar target detection is also proposed by defining the distance between the null and alternative distribution on statistical manifold. The information geometry method to radar target detection is achieved by comparing the distance between oberserved distribution and the hypothetical distribution when target exists or not. Moreover, it is easy to be accomplished by translating radar target detection problem into geometry problem on statistical manifold. Finally, detection performance of information geometry method and likelihood ratio detector is compared by simulations. [ABSTRACT FROM AUTHOR] |
