3.1 Introduction

Detection, identification, and tracking of spatial phenomena (DITSP) using geographically distributed sensors have become important tasks in several environmental and infrastructure applications. Recently, these problems received renewed attention in part due to the advances in sensor network technologies that provide newer and flexible solutions and deployments. Typically, the underlying phenomena is “measured” at discrete points in space and time by the sensors, and the overall task is to “estimate and track” the parameters of phenomena such as origin, velocity, strength, and dispersion ...
