Gradient field localization, such as chemical and heat source location, is a complex problem, yet few designs have been proposed. Examples are locating fires, thermal leaks in insulation, explosive vapors, illegal substances, and chemical leaks. In this paper, we propose one 4 sensor stationary array to localize the direction-of-arrival (DOA) of a temperature source and model the approach on our previous biologically-inspired array processing technique. Several variants of the algorithm are shown, and with each degree of sophistication, it significantly reduces the DOA variance caused by noisy measurement conditions. Next, a clean 4/8-sensor version of the array was constructed, and it is shown that sensor cooperation improves the adaptation in diffusive, turbulent, and noisy environments.
