红外玫瑰扫描系统是利用玫瑰扫描机构和红外单元探测器构成的一种亚成像系统，红外探测器瞬时视场小，它就是利用这些小的瞬时视场来实现对整个观测空间的扫描。而此类系统存在覆盖率和成像空间分辨率低，无法辨识目标细节的问题。通过对初始相位的控制，将多帧亚图像经过重叠，可以得到准致密图像，大大提高成像空间分辨率。通过研究玫瑰扫描成像特点，提出了一种简单有效的确定初始相位的计算方法。最后，经两个实例验证，在得到高分辨率的前提下，大大节省了系统扫描时间，证实了此方法的高效性和可行性。

The infrared sub-image system with rosette scanning is composed of a rosette scanning mechanism and a single-element infrared detector. The infrared detector’s instantaneous FOV is small, with which the rosette scanning cover the total FOV. However, this system has a low overlay ratio and a low resolving power of the imaging space. It also can’t recognize the objective details. Through the control of the initial phase and overlapping the multi-frame sub-images, Quasi-dense image can be achieved and resolving power of the imaging space is greatly improved. By studying the rosette scanning image features, this paper proposes a simple and effective method of determining the initial phase. At last, verified by two examples, this method saves system scan time greatly under getting high resolving power, so it is efficient and feasible.
