ABSTRACT:
A method of tracking an object including the steps of: collecting N measurements of range Riand Doppler velocity Diassociated with the object from a plurality M of radar sensors Sieach measurement being assigned a time stamp ti; time aligning each Range Rimeasurement to a common time stamp tNto provide a corresponding time aligned range Pifor each of the N measurements; using each time aligned Range measurement Pito define a corresponding spherical equation such that N spherical equations are defined; and deriving analytical solutions from three of the N spherical equations to determine the position vector of the object.
