Paper Abstract

We have developed a high fidelity seeker simulation including point spread function, pixel fill factor, read noise, background radiation, fixed pattern noise, and smearing due to relative platform/target motion, which is fully described in a previous paper. In this paper we report on enhancements to this model and integration of the seeker model with a six degree of freedom (6dof) missile model. The enhanced seeker model is applied to a photon starved scenario and used to evaluate the tradeoff between a high quantum efficiency, low noise CCD and a photon counter exhibiting only photon noise but significantly lower detection efficiency. It is shown that even very small amounts of read noise bring significant track accuracy penalties in low background situations. The 6dof simulation employs an object oriented architecture and is implemented in C++ for Windows. It simulates target position and missile (or observing platform) position and attitude versus time, as well as the missile guidance and control systems. This allows interactive tradeoffs between seeker design and guidance and control system design to be evaluated early in the design cycle. An example of such a tradeoff is presented.
