| 摘 要： | 为了提供更适用的地表参数反演方案,对Njoku等模拟AMSRE-E数据的多参数反演工作重新进行正向模拟和算法改进,算法用MATLAB开发实现.反演结果表明,改进后的反演方法不仅在精度上略高于原方法,而且还能反演裸露地表可实际测量的粗糙度参数,并在更大的植被含水量范围内达到较高的反演精度.

| Abstract: | In order to provide more suitable surface retrieval methods, the authors reconducted forward modeling and made algorithm improvement for multiple parameters retrieval of AMSRE-E data simulated by Njoku-developed Levernberg-Marquardt iteration algorithm, and realized project code in MATLAB. The result shows that the improved retrieval method not only has somewhat higher precision than the original method but also can make retrieval of measurable roughness parameters of the exposed surface. In addition, it can attain relatively high precision in a wider water content range of vegetation. |
