One of the more expensive components of a precision guided rocket is the seeker. As repeatedly demonstrated by the Hellfire missile, SAL seeker technology is quite mature, but it is far too expensive for use on a low-cost guided missile. Several programs have been established at various times to address this need, the most recent being APKWS and it s successor, APKWS II. In this SBIR, Polaris Sensor Technologies is proposing a system approach to provide a low-cost, semi-active laser, strap-down seeker. By optimizing the response of high-dynamic-range Position Sensing Detectors or PSDs, our concept will significantly reduce the cost of SAL seeker technology by eliminating the expensive domes, gimbals, and traditional optics typical of current-day SAL seekers. During the Phase I effort, Polaris took the proposed concept and the proposed objectives and successfully demonstrated the feasibility of our approach. The tasks completed under Phase I not only met all of the objectives agreed upon in the Phase I Kickoff meeting but additionally designed, built, and tested custom electronics to demonstrate a pulse-sensitive PSD. The Phase II objectives, schedule, work plan, and expected results are discussed. The Phase I results are also presented and discussed.
