“…However, the traditional particle filter algorithm is easy to lose the validity and diversity of samples, resulting in sample dilution. Three feasible schemes [18][19][20] are proposed, increasing the number of random sample particles, introducing resampling mechanism and selecting a reasonable density function. However, increasing the number of particles will increase the time complexity of the algorithm.…”

Aiming at the traditional integrated fuse information fusion method that cannot simultaneously obtain high‐precision burst control parameters such as burst delay time, azimuth angle, and detection angle, the infrared imaging detector and range finder information fusion method based on particle filtering with BAS algorithm is proposed. Under the centralized information fusion structure that can obtain higher accuracy, first, use a faster linear interpolation method to realize the time alignment of the two asynchronous sensors. Second, for the strong non‐linear observation model in the missile target rendezvous model, use a particle filter framework that is not affected by the nonlinearity of the system function and non‐gaussian noise. Finally, Utilizing the single search BAS algorithm with low computational complexity to solve the problem of particle degradation in particle filtering and improve the accuracy of burst control. The experiment shows that in a typical simulation environment, the optimized information fusion method improves the burst delay time accuracy by 61.82%, azimuth accuracy by 66.28%, detection angle accuracy by 36.15%, and simulation time is shorter compared to traditional methods.

The traditional theory of dynamic open-loop control of fuzes has been unable to satisfy the demand for smart fuze control. After analyzing time–space recognition and process control as the basis of fuze detonation control, three key issues of smart fuze control are summarized herein. Furthermore, three types of controllers are constructed, namely, detection, state, and detonation controllers, which achieve the precise detonation control of ammunition under the interference of complex multi-physics environments, ensuring efficient damage to the target. Based on the above-mentioned controllers, the design theory of the ternary cascade control of the smart fuze is established. In addition, the technical system of the ternary cascade control theory is reviewed, and the latest progress in control strategy design, environment modeling, target modeling, and other fields is summarized in detail. Finally, the development demands and technology trends in intelligent fuze control technology for future intelligent warfare are explored.

The paper deals with the development of a motion correction system for an unguided rocket of a certain class. The existing method for calculating the rocket flight range based on the dependence of flight path on the initial rocket pitch angle and average parameters of disturbing effects does not provide the required accuracy of the specified flight range. This is mainly due to uncontrolled range wind deviations in the flight area. At the same time, conducting test rocket launches to identify dispersion characteristics and improve the target accuracy leads to significant material costs. Therefore, computer simulation is the most promising approach for studying rocket dispersion laws and developing a motion correction system for the unguided rocket on this basis. When developing the correction system, classical differential equations were used describing the aerodynamics of a variable-mass rocket, as well as adaptive control methods with a reference model. As a result of the study, a method for recording a program that implements the reference model on the Arduino Due platform was developed. A general Simulink model that simulates the process of rocket flight path correction was built. A half-scale rocket flight model with a correction block was developed. Based on this model, a series of experiments were carried out, which showed a high degree of rocket target accuracy due to rocket path correction. The results make it possible to take the developed system as a basis for developing a practical path correction system for Grad rockets
