TargCoordVec
[K,rhoP,rhoT,upECF] = TargCoordVec(G)
Returns unit vectors in earth-centered fixed (ECF) coordinate system defining a target-based coordinate system from a platform to target, with propagation vector K from platform to target, and transverse directions oriented with the velocity vector of the target.
