Abstract
A method for sequence image generation of dim point moving targets in complex star background was presented based on STK/matlab software. Firstly, the starry background modeling process was analyzed; then, the satellite disturbance and noise that affected the point target imaging were detailedly discussed to make sequence images simulated closer to the real world; and besides the space target was modeled and its relative geometric relationship with the observation satellite was predicted by the STK software, at the same time the visibility of high earth orbit was systematically analyzed. In addition, a simple and convenient method to calculate the space target visibility criterion was given. By taking into account of various factors that impacted the visibility of high earth orbit target, the space target orbit prediction data was generated by STK and then matlab software was adopted to simulate the sequence image. It's useful in providing space environment for detection and tracking space target.
