The principal to get target speed by DEMON spectrum is given, and the computing efficiency for this method is also analyzed by the simulation in this paper.
给出了通过DEMON频谱获取目标速度的方法,并通过仿真对联合解算效率与纯方位法进行了比较。
Firstly, the spectrum data is processed by principal component analysis ( PCA), then, an estimating model based on a Gaussian kernel function is set up using the PCA data and their temperatures.
首先对历史光谱数据进行主成分分析(PCA)处理,再根据PCA特征数据与其表面温度的对应关系建立温度的估计模型,该模型是基于高斯核函数的。
