| 摘 要： | 通过模拟计算分析，探讨了光学Ｈａｄａｍａｒｄ编三成象技术对运动目标成象的特点，指出在一帧编码时间内，目标信号的变化会造成象素之间的交互干扰，并且干扰随信号变化量的增加而增强，所以编码成象较适应于低速目标的观测。

| Abstract: | The characteristics of Hadamard transform image for moving targets is analyzed.Based on some target models,numerical simulation was carried out.Results show that signal variations produce interference between pixels,and an increase in speed of moving targets will cause the degradation of the image quality.So Hadamard transform image is suitable only for stationary targets observation. |
