Abstract

The classical approach for designing sensor systems is to make the blur circle from a point- source object be approximately the same size as a pixel. Problems arise, however, when the blur circle moves around on the focal plane and energy is lost not only in the gaps between pixels but is also spread among multiple pixels. This paper presents some of the details of how a high-fidelity threat-object scene generator, a detailed seeker model, and a signal processing algorithm have been integrated into the Kinetic Energy Weapons Digital Emulation Center (KDEC) six-degree-of-freedom missile simulation. Several different sensor design tradeoffs are examined such as variations in detector size, aperture size and staggered pixel rows. It is shown how spatial sampling of the moving blur circle can have a detrimental effect on the tracking accuracy and final miss distance of guided-missile systems. Point-source and extended (imaged) objects are examined to show the importance of investigating the effects of sensor design on the entire missile system.
