The phase controlling technology of super-resolution imaging of infrared rosette scan

The subimaging target recognition system of infrared rosette scanning is the main optimal terminal guidance system, however, the resolution of the imaging space is not high. Based on the optimal controlling rule of scanning parameter, this paper proposes the phaseshift parameter controlling method which is performed through shifting the phase and overlaping the multi-frame phase diagrams. Thus, high resolution of imaging space under the condition of high speed, nice efficiency is achieved. The experimental results of DSP system show that this technology improves the image resolution of the system effectively.
