Geometric rectification problems of the strapdown scene matching for aircraft with attitude variances are investigated. Firstly, by analyzing the main factors causing geometric distortion in the process of real-time image capturing, two coordinates system are established, the real-time image distortion is classified, and the distortion mathematic models are proposed. Then, according to the altitude...
An equation about the equivalent capacitance and the potential coefficients of a conductor system is given. On the basis of the equation, a matrix computation method of the equivalent capacitance of a conductor system is brought forward. The procedure of the method is as follow: write out a matrix about the conductor system according to some rules, firstly, and secondly, do some calculations. The...
After the instruction of FCS and Time, a new proxy signature is proposed. The new scheme not only has the properties of proxy signature, but also greatly improves the security.
