Aiming at the problems of twin-barrelled naval gun weapon automaton axis angle design, through establishing system error model and optimization model, the optimal angle of automaton axis and the effective firing area of the naval gun were determined. In terms of meeting solution problem of the gun fire control, a correction method was presented to calculate future position. The simulation and analysis show that, the firing effectiveness can be improved while the automation being in a certain range. A kind of feasible method is provided for twin-barrelled naval gun automaton axis angle design and corresponding fire control correction. Source

MUSIC algorithm can't estimate the DOA of coherent signals, and traditional decorrelation methods based on array signal processing theory are not suitable for single acoustic vector hydrophone. The single acoustic vector hydrophone can be treated as a scalar sensor array. Based on array signal processing theory, the modified DOA estimation algorithm is constructed. The operation principles of this algorithm are describes in detail. We compare the resolution of the proposed algorithm with the high-resolution multiple signal classification (MUSIC) method. Simulations show that the proposed method performance is superior to MUSIC algorithm in the case of correlated sources signals. The simulations have proved the effectiveness of this new modified MUSIC algorithm. ©2010 IEEE. Source

For the extended life of underwater weapon samples, demonstration of the working reliability is an important basis for the overall implementation extended life measures. The demonstration test scheme by GB5080.5 need to many samples, so gives a Bayesian certification scheme to reduced the sample. By mining the messages of the working reliability before extended life, land equivalent trial and sea trial, thereby give a new method constitute demonstration scheme. The example shows that the method is premise the quality of demonstration while a great deal of sea trial sample is saved, and it is satisfy the need of practical engineering. Source

According to the function and characters of air defense using the ship borne guns, a kind of minimum deflection indetermination MADM method with the attribute value of interzone data, completely unknown attribute weighing and the subjective bias towards projects of the commander is presented. Membership functions are given. With the measured data of the sensors, the attribute statistical inference intervals are given as the elements of the decision matrix. Considering synthetically the object attribute data of the objects from the sensors net and the subjective bias to objects of commander, a minimum deflection indetermination MADM method is set up. Finally, a numerical example of aerial defense object threat assessment is given to show the rationality and effectiveness of the method. Source

Consider the influence of space and time, dynamic weapon target assignment (DWTA) problem is a complex problem. First of all, the time restriction and space restriction for assignment are analyzed, and an assignment mathematic model is established. Secondly, an adaptive memetic algorithm is proposed to solve this problem. This algorithm adopts genetic algorithm as the global search tactic, and simulated annealing algorithm as the local search tactic. Meanwhile, a time control strategy is used to control the algorithm outputting a satisfied result in regulated time. At last, some simulated results testify this algorithm's feasibility and effectivity for dynamic assignment issues. ©2010 IEEE. Source
