This thesis establishes constrained motion model and sensor model of a mobile robot to represent mobility and perceptivity, respectively, and defines the k step reachable region to describe the states that the robot may reach. We show that the calculation of the k step reachable region can be reduced from that of 2k reachable regions with the fixed motion styles to k + 1 such regions, and provide an algorithm for its calculation.

In this chapter, three kinds of target recognition methods are performed, which are:①Target recognition method based on the description of polarization parameter plane. The echo polarization states of target are projected onto the polarization state plane described by the ellipticity ε and the tilt angle τ of the polarization ellipse, the change of parameter following ferquency becomes the chart. According to the changing trait of the chart, the multidimensional polarization feature space of target has been contructed. Furthermore, a series of polarization feature parameters used in designing the structure of target recognition device are extracted, and they are insensible to the posture of target.②Target recognition method based on the description of Poincare polarization sphere. The echo polarization states of target expressed by Stokes vector are projected onto the Poincare polarization sphere. The conception of polarization ferquency stability, which is used in describing the dynamic distribution characteristics of the target echo polarization states on Poincare polarization sphere, has been defined. A group of polarization feature parameters used in designing the structure of target recognition device are extracted, and they are insensible to the posture of target.③Target recognition method based on the description of frequency sensitivity. In accordance with the conception of the polarization state distance defined on Poincare polarization sphere, the frequency sensibility of the physical structure property of target has been investigated, the frequency distribution feature curves in PSD domain are obtained, and targets'features are extracted by means of the curve-fitting method with Least Square Criterion.

A common heating oxidation device(fig.1)is to place a silicon plate in a quartz crystal glass reaction chamber. In the reaction chamber, a electric resistant wire heating device heat up the chamber to a certain temperature(usually, the temperature is 900~1200℃. In a special condition, it can be descended to under 600℃). When oxygen or water vapour pass through the chamber(typical gas flow speed is 1cm/s). A chemical reaction is generated on surface of the silicon plate.
