Closed form 3d polynomial solution from multiple 2d sensors

Abstract

transform analysis of human activities using through-wall noise and noise-like radar. This paper presents a closed form solution for a 3D polynomial using measurements from multiple 2D (passive) sensors. This solution is useful in a multiple sensor tracking environment when initializing more complex 3D estimators with passive sensor measurements and when correlating tracks across multiple sensors. The closed form solution is also extended to include active sensors as one or more of the algorithm's contributing sensors.
