Due to the disadvantages of traditional localization & tracking at those aspects of users' privacy protection, system configuration and maintenance, this paper proposes a new approach for infrared object localization and tracking with distributed wireless pyroelectric infrared sensors. A hierarchical architecture of visibility of Fresnel lens array is presented with spatial-modulated Field Of View (FOV). Firstly, the FOVs of Fresnel lens array in a sensor node are modulated to achieve a single Degree Of Freedom (DOF) spatial partition; then the localization algorithm is proposed to coordinate multiple sensors nodes to achieve two DOF spatial partitions.
