Target super-speed detection is the base of target real-time tracking and attacking of infrared terminal-guidance miniaturized system with the optimal rosette scan. Through the research on the optimal controlling rule and model of scan parameter, and the fast and efficient image target detecting method, this paper proposes the phaseshift parameter controlling method, and the equation for imaging under the condition of super speed, nice efficiency and high resolution. The phaseshift controlling sequence, and accordingly, the overlay ratio and the resolving power of the imaging space, and the property of operating area are derived. A subarea target detection technology is advanced. The simulation results are given out.
