The infrared image in the sea background usually contains random noise, sea waves, fish scale light and other clutter. Sea waves and fish scale light interference are similar to small infrared targets, so it is difficult to eliminate such interference and detect small infrared targets quickly and accurately. In this paper, a small target detection method based on non-local similarity is proposed. The interference is eliminated by using the class feature similarity of interference and the overall feature uniqueness of the small target. Firstly, this paper performs filtering to remove random noise, and the suspected small targets can be extracted by executing Top Hat filtering. Secondly, a multi-feature vector is constructed for all suspected targets. Finally, this paper analyzes the characteristics of different interference and executes clustering step by step. The wave edge interference and fish scale light interference can be eliminated in turn. Feature threshold is set based on the interference that has been identified to obtain the true small infrared target according to the uniqueness of the characteristics of the true target. The experimental results show that compared with other small target detection algorithms, the proposed algorithm can detect small infrared targets in complex sea background effectively.

In this paper, a docking navigation method for autonomous aerial refueling(AAR) of unmanned aerial vehicles(UAVs) based on a binocular vision system(BVS) is proposed. A BVS simulation platform is built for simulation research purposes. First, unnecessary scene information in the image is filtered through green light-emitting diodes(LEDs) and filters. Then the image is processed via graying, binarization, and median filtering to highlight the connected area of the LED in the image. Subsequently, the center of mass of the connected area is selected as the feature point(FP), and the FPs are described using an improved Haar wavelet transform. The multidimensional description vector of FP is obtained and matched. Finally,the position and pose of the refueling cone sleeve are estimated. Simulation results show the effectiveness of the presented AAR navigation method.

the airborne information processing system, which is subordinate to the avionics system, is the basic sub-system performing information data processing in the aircraft platform. It provides computing, storage, information transmission and other basic resources for the whole aircraft, and can provide various functions and services such as computing, management, configuration, scheduling and other. The future development of airborne information processing system should be driven by the basic computer technology development and military requirements of aircraft platform. From these two perspectives, on the basis of full analysis of the development status, this paper summarizes the future airborne information processing system architecture and some key technical characteristics of the processing platform, laying a foundation for future research work. © 2020 IEEE.

Mode decision-maker is a critical component in the logic-based Integrated Estimation and Guidance(IEG) system. For the best possible estimation and guidance performance, the mode decision delay of the mode decision-maker should be limited to a range as small as possible. This paper presents a numerical method for computing the maximal admissible mode decision delay that varies with time-to-go. Particular attention has been paid to highly maneuvering target interception in terminal guidance. The results of this research offer useful guidelines for the design of the mode decision-maker in IEG systems.

Under the systematic combat mode, aviation cyberspace is a complicated, dynamic and confrontational information space. How to evaluate network security situation efficiently and precisely will lay a solid foundation for the establishment of architecture of security protection technology. Given that the security attacks on the aviation combat field appear covert, dynamic and intellectualized in the future, in order to analyze and recognize a variety of different threats correctly and fastly, the architecture of security protection technology for aviation cyberspace is proposed in this paper. Furthermore, we give the detailed description of key technologies related to it. Consequently, based on the theories and technologies illustrated by our designed architecture, the intelligent security protection system oriented to aviation cyberspace could be implemented. © 2020 IEEE.

Terminal Angle Constraint Guidance Law Based on SDRE Method 4

Terminal Angle Constraint Guidance Law Based on SDRE Method

In this paper, a new guidance law based on SDRE method is designed to solve the problem of terminal angle constraint of a missile by using nonlinear kinematics model and dynamic model of a missile. The constraint of collision angle can be realized by the guidance law under the condition of satisfying the requirement of miss distance of terminal guidance. In addition, the guidance instructions in the form of feedback and the analytic solution of the guidance law are obtained in the two-dimensional plane. Compared with previous terminal guidance methods, the advantage of the method is that it does not depend on the estimation of the time to go. The effectiveness of the proposed guidance law can be verified by digital simulation. © 2019 Published under licence by IOP Publishing Ltd.

For multiple embedded computers working together, the functional failure resulting from the underlying hardware or system crash will cause a sudden abort of applications. Different types of applications may have security requirements for data isolation and access control. Therefore, we propose a scheme to implement multi-level security domain dynamic management oriented embedded computers based on MILS architecture. Firstly, the scheme builds local security policy items and access control lists according to type, function and security level. After that, security domain of all applications is constructed to achieve the safety purpose that applications can perform migration cross partitions and cross platforms. Our experiments and analysis show that the proposed scheme is feasible and correct. © 2019 IEEE.

The effective fault diagnosis is the basis of system reliability and accuracy in SINS/BDS tightly-coupled integrated navigation system. The state equation and measurement equation in the launch inertial frame are modeled.
