In order to realize the staring search imaging with a certain overlap of long strip area in the vertical direction of high resolution array camera, a pendulum staring search imaging model is designed with the staring gesture and earth movement complement. Based on the division of the strip layer by layer and the construction of three-dimentional movement rate, the guiding strategy of real-time posture change and earth rotation compensation is designed. Besides, the pendulum adaptive search imaging parameters and real-time variation point orientation are calculated, and the effect of attitude control precision on imaging is analyzed. Finally, a ground scaling simulation experiment is carried out through the CMOS prototype, the attitude control three-axis flotation simulation platform and curved LED target system. The result shows that a gradually variational strip area with the inter frame overlap ratio more than 85% can be obtained using the pendulum staring search imaging when the pendulum staring adaptive search imaging parameter is 0.95, which is enlarged by four times than the staring imaging area. When the attitude control precision is better than 0.05° and attitude stability is better than 0.003 (°) s-1, the image motion mismatching quantity is less than 0.9 pixel and the corresponding modulation transfer function can reach up to 0.1559.
