Scheduling is an important issue of radar resource management as there is a strong correlation between how tasks should be carried out and the time available to perform them. Multiple Input Multiple Output (MIMO) radar is a new radar technique. The problem of resource management in MIMO radar is important. In this paper, this problem is investigated.
MIMO radar is a new radar technique developed recently. In this paper, a new signal processing method of independent component analysis (ICA) is presented. In the receiver, the ICA is employed to separate each of transmitted signals. And then, the signal is processed using conventional method such as DBF, MTD.
Multiple Input Multiple Output (MIMO) radar is a novel radar technique developed recently. In this paper, the principle of MIMO Radar based on collated antenna is presented and then the data fusion technique for MIMO radar is described. First, each elements of MIMO radar performs detection respectively, and then the results integrated in a center. At last the final detection result is get which includes...
With the popularity of GSM network, GSM terminal equipments are not only used in traditional voice communications, but also be applied in control area more and more widely. Firstly, some typical GSM-based applications and Siemens's cellular engine TC35 are introduced. The principles of SMS-based remote control system are discussed thoroughly, as well as hardware and software. This system makes use...
In this paper, we propose a forecasting model of electric power equipment statement assembled by core vector machines and particle swarm algorithm to improve the accuracy of electric equipment maintenance. The electric power equipment condition forecasting model improves parameter selection problems of nuclear vector regression by particle swarm algorithm, optimizes parameters of kernel function and...
Traditional sculling algorithms make use of incremental output of gyros and accelerometers to design algorithms, when they are applied to fiber-optical gyro (FOG) strap down inertial system (SINS), whose gyros output angular rate signal, we should simulate incremental signals by angular rate, which not only increases design difficulty but also reduce calculation accuracy. In view of this, an improved...
In the analysis of the characteristics of network traffic we proposed a method for web site network security. We separate efficiently users by cookie, analyse user's activity by Hidden Semi-Markov Model, caculate the normal degree and allocate the bandwidth for the normal users. So we can defense DDoS attacks and control abnormal network traffic flow.
One method of obtaining the Taylor Series Expansion Coefficients, which are suitable for engineering application, are presented: Artificial neural network(ANN) , by virtue of its high nonlinear and learning abilities. The Taylor Series ( TS ) can be represented as a standard 3-layers feed-forward neural network after transforming in which the weights are correspond to the Taylor Coefficients. Therefore,...
In the training process of HMM-based speech synthesis systems, the states of the HMM models are clustered based on the context features labeled on the training corpus. A good feature set would enable the synthesis system to generate natural prosody. In this paper, in order to synthesize interrogative intonation, we analyzed the acoustic features of the interrogative intonation and the context features...
In this paper, we present a statistical analysis of the performance of three dimension parametric shape estimators. By using the Cram¶er-Rao lower bound(CRLB), we also generate confidence regions which conveniently display the effect of parameters on the quality of the estimated shapes, as well as allow a performance analysis of the algorithms.
In this paper, we study the controllability for a system of linear parabolic equations. Through Galerkin method, we get the null controllability for this system with the Kalman condition.
In today's increasingly competitive world, Design of Experiments (DoE) techniques are widely used, both by researchers and in industry to minimization of statistical experiments and lowering cost while maximization of result quality. But DoE techniques are various in involved factors and application. One of the most important models that can block 3 nuisance factors is Graeco Latin Square. Considering...
A key technique of wireless sensor networks is time synchronization. This article introduces the definition of time synchronization and suggests a guideline for designing the time synchronization protocol in WSNs, through analyzing the characteristics of the existing typical synchronization protocols and making a comprehensive comparison of the performance of various algorithms.
For all members within a supply chain, effectively managing dependencies is very important. Indeed, as market pressures dictate that today's commercial supply chains provide rapid and efficient supply, the need to collaborate with all members within the supply chain is becoming increasingly critical. As such, there is an emerging need for organizations to understand, formalize, and manage the resulting...
Mining frequent item sets over P2P network is a challenging problem. The obstacles mainly lie in numerous frequent item sets and huge communication cost. To solve the two problems, a maximal item set mining algorithm P2PMaxSet is proposed. Firstly, only maximal item set is considered, which reduces the number of item sets greatly. Secondly, mining results are only interchanged between neighbor nodes,...
