介绍一些Python 的背景知识，包括Python、Python 的起源和它的一些关健特性。一旦你来了兴致，我们就会向你介绍怎样获得Python 以及如何在你的系统上安装并运行它。本章最后的练习将会帮助你非常自如地使用Python，包括使用交互式解释器以及创建并运行脚本程序。(Some Python background knowledge, including Python, Python' s origins and its Key characteristics. Once you got into high spirits, we will introduce you how to get the Python and how to install and run it on your system. The chapter concludes with exercises will help you very comfortable using Python, including the use of an interactive interpreter, as well as create and run scripts.)

Tactically maneuvering targets are difficult to track since acceleration cannot be observed directly and the accelerations are induced by human control or an autonomous guidance system therefore they are not subject to deterministic models. A common tracking system is the two-state Kalman Filter with a Singer maneuver model where the second order statistics of acceleration is the same as a first order Markov process. The Singer model assumes a uniform probability distribution on the target s acceleration which is independent of the x and y direction. In practice, it is expected that targets have constant forward speed and an acceleration vector normal to the velocity vector, a condition not present in the Singer model. This paper extends the work of Singer by presenting a maneuver model which assumes constant forward speed and a probability distribution on the targets turn-rate
