Abstract

We develop methods for detecting and localizing vapor-emitting sources using chemical sensor arrays. Potential applications of these methods include detection of explosives or drugs, sensing leakage of hazardous chemicals or pollution, and studying the environment. We describe the pertinent physical models, develop estimation and detection algorithms, and derive performance bounds. The algorithms are tested numerically and compared with the theoretical bounds
