| 摘 要： | 结合小目标和海天背景本身的特性，建立了一套小目标与背景合成红外热像模拟的物理模型，从而计算得到了一系列小目标与背景的动态红外热像。并且为了模拟经探测器成像后输出的图像，在计算机模拟生成的“目标／背景红外图像”中注入了一种服从高斯分布的噪声。研究结果可以为目标识别等提供模拟的动态红外图像。

| Abstract: | A physical model for infrared thermal image simulating was developed, which takes account of the characteristics of both small target and sea and sky background. The dynamic infrared images of combining target with background were obtained by simulating computation. And in order to simulate the imagesformed by a detector, the noise signals of the detector that are assumed to be Gauss-distributed were added to the combined images. The model and the simulation method can be used to provide simulated dynamic infrared images for target recognition. |
