摘要: 红外玫瑰线扫描亚成像目标识别系统是当今主要的最优末制导系统,但该类系统的成像空间分辨率较低,该文研究了玫瑰扫描参数最优控制准则,提出了扫描初始相位参数控制法,通过改变每帧的初始相位并进行多帧扫描相图重叠,高速高效地形成了高分辨率成像空间。DSP系统实验结果表明,该技术有效地提高了系统的成像空间分辨率。Abstract: 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.
