Trust is an important topic in information security research and is oriented to increase the reliability and performance of a web-based system in open networks. A trustworthy e-learning system is a trust-based learning system which contains reliable serving peers and useful learning resources. In this paper, a survey of trust researches in trust management(More)
This paper develops a technique for fusing data from millimeter wave (MMW) radar and infrared (IR) sensor to track maneuvering target. Modified extended Kalman filter (MEKF) is simple yet very effective in accounting for the measurement nonlinearities. The idea of fusion is to combine MEKF with pseudo sequential filter to obtain optimum state estimates. The(More)
An aerodynamic force and lateral thrust blended control autopilot is designed for the near-space air-breathing hypersonic missile with low overload cruise phase due to angle of attack restriction. The nonlinear longitudinal short-period motion model of a hypersonic missile is built, and several fuzzy control strategies are applied in overload command(More)
Based on multisensor information fusion theory and optimal control theory of structure stochastic jump system, a new guidance law is proposed for air-to-air missiles based on information fusion of active radar and infrared sensor, and its validity is testified by analysis on simulation by building digital model of missiles. Compared with proportion(More)

Traditional algorithms of HF burst signal detection and synchronization acquisition usually can't work well under low signal noise ratio (SNR). Aiming at the character of HF channel, a reliable synchronization acquisition scheme for HF channels based on spectrum analysis method was obtained by modulated m-sequences pilots to get some dispreading gains. The(More)
Bias estimation is a critical problem in multi-sensor tracking systems, and most existing research has focused on the bias estimation of synchronous sensors; however, in practical applications, sensor measurements are usually asynchronous. The primary contribution of this paper is that a novel algorithm using B-spline interpolation time registration to(More)
In order to solve the problem of the distance estimation of the infrared passive system, a distance estimation algorithm is proposed based on the optimal estimation theory of structure stochastic jump system. Considered the rapidity and the limit of the internal storage capacity of the algorithm, a simplified algorithm is derived. And the ability of the(More)
Based on stochastic maximum principle, the optimal control algorithm is proposed for Markov jump system with complete information, further more, the method is extended to Markov jump system with incomplete information. The optimal controller design method is studied with statistical linearization method for Markov jump system with constrained control(More)
In this paper, the problem of sensor registration with range gate pull off (RGPO) deception and time variance biases is solved effectively. The contributions of this paper are that the framework of sensor registration with RGPO are established, and in the measurement model a pseudo measurement only containing time invariance biases is obtained in order to(More)
