Metallic mesh is an important technic approach to realize the stealth of the electro-optical radar. This paper demonstrates the designing thoughts of metallic mesh, and in the conclusion, this paper achieves the integrated design method by analysing electromagnetic shielding, permeability and so on. By using this method, a metallic mesh designing with high electromagnetic shielding is designed, which will make the aircraft gain better stealth effect in combat. © 2018 The Authors, published by EDP sciences.

With the rapid development of multi-aircraft network combat, a new demand for sensor management system is raised. This paper proposes a novel architecture of task-oriented multi-aircraft sensor management system, which is based on multi-agent. According to requirements of multi-aircraft network combat, function division, module definition and mutual information of the architecture is given. A preliminary simulation is carried out to verify the feasibility of the architecture. Driven by missions, this architecture has characteristics of excellent openness and adaptability.

For improving the platform tracking performance, the ground target tracking fusion based on platform-level multi-source heterogeneous sensors was studied. The association of the target's state information was built using gray algorithms, and then the results were further tested by the recognition confidence of target type using evidence theory. Additionally, with assistance of road information, the ground target tracking model sets and filter are designed for the tracking. The effectiveness of the algorithm was verified by simulation.

On the design methods and traditional micro system structures in multiple configurations, there are some certain limitations. In order to resolve the problems of the conventional multiple structures present in the system, new sensors and components are applied in the development of the design method and system configuration. Micro lens, as a kind of typical components, are developing the methodology in research advanced multiple configuration systems. The effect of system evaluated criterion that Modulation Transfer Function (Modulation Transfer Function, the MTF), Energy concentration (Radial Energy Analysis, REA), diffusion (Spot Diagram, RMS) can support our issue qualitatively. Results showed that can not only change systems weight, size and structural stability, but also increase freedom in these kinds design. While improving the implementation of existing multiple path configuration from traditional complex. © 2017 OSA.

In order to improve the resolution of the imaging system, and achieve the theoretical limit, we introduced the technology principle of super resolution restructure from the point of view on theory and engineering. Several methods to realize high resolution restructure configurations are introduced based on theoretical analysis and engineering practice. Then, three kinds of restructure technologies, that prototype, micro scanning and sub pixel are described, and how to decrease their shortcomings are discussed in detail. Furthermore, to improve the band width by reconstruction without the spectral alias in super resolution technologies, a new coding technology combining a optical encoding and the sub pixel is proposed. With the global method, the bandwidth has been amplified by ten times as compared with that of traditional ones. Simulation results show that the system can meet the application requirements in MTF, REA, RMS and other related criteria. Compared with the conventional design, the system has reduced in volume and weight significantly. Therefore, the determining factors are the prototype selection and the system configuration combined optical, electronic and signal processing technologies, and as an important developing trend. © OSA 2017.

To deal with the problem of ballistic reentry target trajectory tracking, a novel particle filter algorithm is proposed to mitigate the particle degeneracy. It can eliminate the inefficient particles by judging the degree of particle degradation at each time and generates new particles based on the estimation state values and their covariance according to the degeneracy ratio of particles. Compared with Standard Particle Filter (SPF) algorithm and Unscented Particle Filter (UPF) algorithm, simulation results show that the proposed algorithm can achieve better tracking performance with lower computational burden for the trajectory reentry target tracking model. Especially in the case of ballistic target maneuver, the performance stability of the proposed algorithm is even more significant.

There are three major contributions. Firstly, applied study on the theory and experiment of single photon detection, including the project and experiment of quantum key distribution. Secondly, based on methods of the selection of detector, main photo electronic system configuration, design and creation, along with the relationship between these to system characteristics have been studied. Thirdly, based on the considerations on the research of image sensor systems on single photon detection, and the total system characteristics are evaluated and discussed in quantity. The results of simulation experiments and theory analyzing demonstrate that proposed method could advance the system validity effectively, and theory analysis and experiment shows the method is reasonable and efficient.
