This paper proposed an improved method on the basis of the extended proportional guidance law. The method solved the weak observability problem of system sate in guided missile attacking maneuvering target. It is simple in form and easy for engineering implementation. This paper set up relative motion model and the observability theory indexes. The improved propotional guidance law is simulated using the MATLAB language. The simulation results show that the method is reasonable, effective and improving the observability.

This paper studies on access control method for automatic test system (ATS) based on access view. The access view of access object is proposed according to the division of test stage, subset and manipulation to units under test (UUTs). Matrix is used to describe the access view and version control is applied for access view. This method provides access control in finer grit.

This paper presents a project of missile guidance system based on the strapdown guidance technology. The project is composed of strapdown seeker and inertial measurement unit. The integrated guidance and control technology have been adopted. The project raise accuracy of missiles on the premise that the low cost should be guaranteed. According to simulation experiment, this paper proves the feasiblity of the scheme, and it has good ballistic missile.

This paper mainly talks about the Covariance Analysis Describing Equation Technique (CADET), which is used for the improved proportional guidance law. Firstly, the principle of this method is introduced. Secondly, the related conclusion and validation of Gaussian assumption is analyzed. Thirdly, an improved augmented proportional navigation guidance law (APNG) is analyzed by this method. Finally, the higher guidance accuracy of this improved APNG is demonstrated by stimulated experiments.
