The 'Within-the-Beam Miss Distance Analysis' presentation is based on the study and development of an electronic subsystem, referred to as the Miss Distance Processor (MDP) and Post Mission Processor (PMP) software package. The MDP subsystem is used to sense the presence of multiple targets within the beam, i.e. field of view, of a single target tracking radar. Off-boresight angle and range errors gathered from each target within the defined window are used by the PMP to reconstruct and predict trajectories, which ultimately lead to the computation of the minimum distance between each target, as well as spatial position of each target. The complete subsystem will have a significant effect on the capabilities of single object tracking radars used on test ranges around the world, giving them the capability to provide spatial information on secondary targets within its beam without the use of multiple tracking stations. The subsystem's primary use is to assist in the accurate measurements of surface- to-air, air-to-air, and sea-to-air ballistic launches against airborne objects. These measurements can be obtained within minutes of the mission, as opposed to conventional techniques used with optical systems. Future capabilities of the system include real time reconstruction and miss distance calculations, construction of submunition trajectories after ejection from the primary projectile, and the use of multiple target video trackers for angle sensing in lieu of radar.
