Behavior models play an important role in analytical simulation system. However, weaknesses such as hard modeling, poor expansibility and little flexibility still exist in current models. In this paper, a behavior model is designed, which consists of Rule-based Expert system and Mission Components. The expert system has high efficient and flexible auto-decision capability. Mission Component provides...
The micromotion of a target will introduce additional frequency modulations on the radar echoes and lead to a contaminated inverse synthetic aperture radar (ISAR) image of the main body. In this letter, a novel ISAR imaging method is proposed for micromotion targets based on the joint sparsity of the main body spectrogram. Under the sparse Bayesian framework, we assign hierarchical priors to the spectrogram...
Traditional data fusion function models only apply to a centralized system. To better the model, on the basis of analyzing the characteristics of the distributed system, in this paper, traditional data fusion function model are extended to the distributed framework from two aspects. Additionally, the distributed data fusion structure model corresponding to distributed data fusion function model is...
In this research-in-progress paper we present a new real-world domain for studying the aggregation of different opinions: optimal urban tactical position selection (TPS). This is an important and foreseeable real world application, not only because cities have been viewed as centers of gravity by military planners throughout history, but also because the military significance of cities has increased...
This paper explores a novel rate control scheme for HEVC, based on Pre-analysis Sum of Absolute Transformed Differences (pSATD). The needs for improving the rate control method of HEVC have been observed since the latest method proposed in JCT-VC H213 is still using the classical quadratic model which is implemented in H.264/AVC. The same rate control scheme on different coding structures will definitely...
Modelling 3D stratum surface is difficult because the number of exploratory holes is usually too small. As an attempt to solve this problem, many interpolation methods were proposed to estimate the surface between the holes. In this paper, we propose an approach to interpolate 3D spatial points and model stratum surface. The curvature of the original surface mesh is embedded into kriging interpolation...
Land surface emissivity (LSE) is an essential parameter in deriving land surface temperature form remote sensing data. According to the single channel characteristics of HJ-1B Infrared Scanner (IRS), a combined method for estimating LSE was proposed based on the vegetation cover method and classification-based method. The proposed method requires inputs such as static land cover product, vegetation...
Testability is a significant design feature for system, which has gong through five stages such as External Test, BIT (Build-in Test), Intelligent BIT, Comprehensive Diagnosis and PHM (Prognostics and Health Management), has greatly improved the maintainability, reliability and availability of the modern weapons especially in electronic systems [1]. Meanwhile, in the process of the researches on systems...
Extracting question-answer pairs from online forums is a meaningful work due to the huge amount of valuable user generated resource contained in forums. In this paper we consider the problem of extracting Chinese question-answer pairs for the first time. We present a strategy to detect Chinese questions and their answers. We propose a sequential rule based method to find questions in a forum thread,...
