用两种递推最小二乘辨识的方法辨识吹风机函数。在加白噪声和有色噪声的情况下观察变化。两个辨识的结果与实际输出很接近，但是都会比实际的要大一点。有可能是对有色噪声的估计所引起的。噪声的增加不明显。(Identification by two recursive least squares method to identify a hair dryer functions. Observe the changes in the plus white noise and colored noise situations. Two identification results with actual output is very close, but it will be bigger than the actual. There may be an estimate of colored noise caused. Noise increase is not obvious.)

目标跟踪问题的应用背景是雷达数据处理，即雷达在搜索到目标并记录目标的位置数据, 对测量到的目标位置数据（称为点迹）进行处理，自动形成航迹，并对目标在下一时刻的位置进行预测。下文简要讨论了用Kalman滤波方法对单个目标航迹进行预测，并借助于Matlab仿真工具，对实验的效果进行评估。里面包括三个源程序，和一份实验报告，里面有算法的详细分析和情景假设。(Application of target tracking radar data processing background, that is the search radar to the target and record the location of the object data to the target location of the measurement data (referred to as Plot) for processing, automatic track formation, and the target in the next time to predict the location. Briefly discussed below, using Kalman filtering to predict a single target track, and the help of Matlab simulation tools, experimental results for evaluation. Which consists of three source code, and a test report, which has a detailed analysis of the algorithm and the scenario assumptions.)
