Based on error classification and closed loop correction principle of closed loop anti-missile shipborne gun, the simulation model of all kinds of firing error sequence in a fire process was established. The kalman filter equation used to estimate the miss distance was proposed. So the miss distance estimation and error correction process of closed loop anti-missile shipborne gun were simulated in more detail. According to the characteristics of coming missile target which closed loop anti-missile shipborne gun fire, the models for future position and hitting radius of target calculation were established. In order to construct complete simulation model of closed loop anti-missile shipborne gun firing missile target in an airway, the simulation methods of hitting event and killing target event were introduced, and the simulation time determined method was demonstrated. At last, the simulation result was listed and analyzed simply.

A preemption MO particle swarm optimisation algorithm is designed and realised. By analysing the particularity of military navigation, the paper has proposed the model of warship course optimisation problem in island region based on multi-objective optimisation. Analysing the pluses and minuses of several kinds of multi-objective particle swarm optimisation algorithms at present, aiming at the deficiencies of these algorithms, the paper has proposed a preemption multi-objective particle swarm optimisation algorithm for warship course optimisation problem. Comparative method is adopted to update local optimum P i. At the same time, propose the method based on preemption strategy, maintaining the colony variety strongly. Lastly, adopt the method of infeasibility degree to deal with multi-obligation. The experiment results demonstrate that the proposed algorithm can solve warship course optimisation problem well, improving the performance on generation distance, spacing and error rate.

The main idea of this paper is to calculate the entire process capability of the Complex Product Machining Process (CPMP) based on modified tradition process capability index and then further decide the improvement orientation and size to individual process parameter through sensitivity analysis. We illustrate the method by a three-stage machining process. The results have shown that the proposed method could significantly improve the process capability. © (2012) Trans Tech Publications, Switzerland.

The most common method of extremum searching for linear frequency modulation (LFM) signal in fractional Fourier domain is the step-based algorithm. But this method is inefficient and time consuming, which affects the application of fractional Fourier transform. In order to overcome this shortcoming, the particle swarm optimization method is introduced and applied successfully in fractional Fourier transform. The influences of different particle numbers and inertia weights are talked about and analyzed extensively. Simulation results show that the performance of particle swarm optimization method is much better than that of the step-based method. It seems that the particle swarm optimization method with proper linearly decreasing inertia weight strategy is more preferable in terms of efficiency, precision, and resolution. ©2010 IEEE.

An adaptive filter method of linear frequency modulation(LFM) signal in white noise is discussed, and a LFM signal is produced. The LFM signal is transformed to sinusoid signal by Fourier reverse transform(FRFT). The adaptive filter, which can be replaced by swept filter, is implemented in domain u, and the filtered signal is gained with the fractional FRFT. A detailed analysis of the method performance proves that the method performance depends on adaptive filter. When LMS algorithm is used, the performance of ALE is decided by step parameter, and the step parameter is selected in practice. At last, Simulation results show that this filtering algorithm is simple to commutated and easy to implement.

Anti submarine warfare is the problem of searching and relocating the submarine after momentarily revealing its position. The conventional submarines run on its batteries when submerged and the submarine's evasion effect is constrainted with not only its top speed but also its battery energy.The conventional submarine's velocity and energy are two important constrained conditions in escaping. With analyzing the typical anti-submarine warfare model and process, the Game Theory is applied in researching the submarine evasion effect constrained by the submarine's velocity and battery energy. © 2011 IEEE.

The conventional submarine has the disadvantages of not-so-fast evasive speed, and the limited capability of torpedo countermeasure systems. There are two types of countermeasures: decoys and jammers.A successful anti-torpedo tactic should consist of the deployment of mixed decoys and jammers and the coordination with the submarine's maneuver. This paper would like to discuss the anti-torpedo tactics from the classical viewpoint A simulation scenario is implemented in order to study the interaction among the submarine, torpedo,decoy and jammers.After applying the evolutionary algorithm, it is interesting to discover some points about anti-torpedo tactics using a mix of decoys and jammers that would make a significant contribution to the survivability of submarine in the torpedoes engagement scenario. © (2011) Trans Tech Publications.

To explore the role of multipartite entanglement in Grover's algorithm, we generalized the Meyer-Wallach measure to include all possible bipartitions of the system, and use this generalized measure as the quantify of multipartite entanglement. It is shown that along with the bipartite entanglement during the process of adiabatic quantum search algorithm, multipartite entanglement also exists and evolution with the system. Moreover, similar scaling behaviors show both in bipartite and multipartite case. © 2012 IEEE.
