In order to improve detection system robustness and reliability, multi-sensors fusion is used in modern air combat. In this paper, a data fusion method based on reinforcement learning is developed for multi-sensors. Initially, the cubic B-spline interpolation is used to solve time alignment problems of multisource data. Then, the reinforcement learning based data fusion(RLBDF) method is proposed to obtain the fusion results. With the case that the priori knowledge of target is obtained, the fusion accuracy reinforcement is realized by the error between fused value and actual value. Furthermore, the Fisher information is instead used as the reward if the priori knowledge is unable to be obtained. Simulations results verify that the developed method is feasible and effective for the multi-sensors data fusion in air combat.

In this paper, we study the problem of tracking aerial targets in a modified spherical coordinate system using an on-vehicle tracking system using infrared sensors. In this challenging scenario, to solve the problems of poor calculation stability and large amount of calculation of the traditional unscented kalman filter algorithm, this article introduces and adopts an improved unscented kalman filter algorithm. In Sigma sampling, the error variance matrix uses singular value decomposition (SVD) to select the simplex with the smallest skewness. Compared with the estimation algorithm based on the standard unscented kalman filter, the new algorithm effectively reduces the state estimation error and improves the tracking stability and tracking accuracy.

This paper presents a retractable infrared laser characteristic fusion target design configuration. In this configuration, the folding mechanism provides the retraction and playback function to drive the simulated target to extend in the length direction, and the extension length can be adjusted according to the background and scene requirements. The simulated target has both infrared and laser characteristics, which can provide a fixed laser reflectivity and cross-sectional area of the characteristic body target. At the same time, the characteristic body target has infrared radiation characteristics of 35um and 812um bands, respectively, for detection and recognition of high-sensitivity infrared detector, and for the verification of laser range finder's ranging ability. © 2020 SPIE.

In this paper, a comprehensive test environment is designed to simulate one or more enemy laser sources with different characteristics in the laboratory, which can be used to test the main technical specifications of the laser alarm system. The same optical path as the laser source is also the infrared target source, which provides targets with infrared characteristics for tracking and performance measurement of infrared interference systems. At the same time, the environment is dynamic, which can simulate the relative motion of the carrier and the target machine, and investigate the dynamic performance index. The establishment of this environment can test the main performance indexes of laser alarm system and infrared interference system, and can investigate the stability of the index in dynamic environment. © 2020 SPIE.

In order to improve the stability accuracy of the photoelectric stabilized platform, this paper uses a coarse-precision combined control based on a fast mirror to achieve the secondary stability of the photoelectric stabilized platform. This method feeds back the residual error of gyro compass to the fast reflector, and adjusts and compensates it through the optical path, and the fast reflector has a higher working bandwidth and can greatly attenuate the disturbance. In this paper, the working principle of the fast reflector is introduced first, and then the second-level stability experiment is carried out by combining the fast reflector with the actual two-axis two-frame photoelectric stabilized platform mechanism. The experimental results show that under the action of a sinusoidal disturbance of 5Hz and 0. 12°, the stability accuracy of the platform at the first stage of stabilization is 11.8 μrad. After the second-stage stabilization of the fast mirror, the stability accuracy of the platform reaches 5.6 μrad, and the performance is improved by 52.5%. The results show that this method can effectively improve the stability accuracy and performance of the platform.

Unmanned Aerial Vehicles (UAVs) have shown their superiority for applications in complicated military missions. A cooperative attack-defense decision-making method based on satisficing decision-enhanced wolf pack search (SDEWPS) algorithm is developed for multi-UAV air combat in this paper. Firstly, the multi-UAV air combat mathematical model is provided and the attack-defense decision-making constraints are defined. Besides the traditional air combat situation, the capability of UAVs and target information including target type and target intention are all considered in this paper to establish the air combat superiority function. Then, the wolf pack search (WPS) algorithm is used to solve the attack decision problem. In order to improve efficiency, the satisficing decision theory is employed to enhance the WPS to obtain the satisficing solution rather than optimal solution. The simulation results show that the developed method can realize the cooperative attack decision-making. © 2021, CC BY.
