In this paper, the geometric structure for normal distribution manifold, von Mises distribution manifold and their joint distribution manifold are firstly given by the metric, curvature, and divergence, respectively. Furthermore, the active detection with sensor networks is presented by a classical measurement model based on metric manifold, and the information resolution is presented for the range and angle measurements sensor networks. The preliminary analysis results introduced in this paper indicate that our approach is able to offer consistent and more comprehensive means to understand and solve sensor network problems containing sensors management and target detection, which are not easy to be handled by conventional analysis methods. ;40:6332-6347.

6333manifold and information resolution to the analysis of sensor networks are explored to gain a better understanding and more comprehensive investigation of sensor system issues for target detection and tracking based on the joint distribution manifold.The outline of this paper is organized as follows. In Section 2, the mathematical background about information geometry is stated comprehensively. The geometric structure about the voM distribution manifold is presented in Section 3. The applications about the joint distribution manifold are presented and analyzed in Section 4. Finally, some conclusions are given at Section 5.
STATISTICAL MANIFOLDNow, we consider the parameterized family of probability distributions M = {p(x| )}, where x ∈ R m is a random variable and = ( 1 , · · · , n ) is a real vector parameter to specify a distribution.Definition 2.1. The probability distribution family M = {p(x| )} is called as a statistical model, if it satisfies the following regularity conditions:
