Single-Point Bistatic Track Initialization Using Doppler in 3D
David Frederic Crouse · 2018
The first two moments of a converted bistatic range (delay)-direction-cosine-range-rate measurement are derived taking into account the Doppler information and maximum bounds on the target velocity in orthogonal unobservable directions. Cubature integration is used to very efficiently evaluate the necessary multivariate integrals allowing correlations between measurement components to be easily taken into account. Such single-point track initialization is useful in many tracking algorithms, such as some variants of the joint integrated probabilistic data association filter (JIPDAF).
