The precession feature of space target provides an effective approach for target recognition. However, with the requirements that target detection and tracking to be completed successfully before the processing of precession features extraction can be implemented, the existing methods demand radar resources allocation for target detection, tracking and feature extraction, respectively, thus reducing...
Space target recognition is one of the radar's significant tasks. The separation of group targets is the basis of the target recognition when several targets are within a range cell of one radar beam. In this paper, a method for group targets separation based on high-order moment function and empirical model decomposition (EMD) is proposed. The first step is deriving the high-order moment function...
The mission of imaging is not considered in existing resource scheduling policies of the multifunction phased array radar (MFPAR) which usually need to separate a fixed part of resources for imaging. Cognitive imaging is introduced firstly, and then a novel adaptive scheduling algorithm is proposed, which is based on sparse-aperture cognitive ISAR imaging. In the proposed algorithm, MFPAR could track,...
Intellectual capital is one of key resources of dynamic capabilities of salt industry in the knowledge economy era. Based on dynamic capabilities, the H-S-R model of intellectual capital management of salt industries has been proposed and an integrated and comprehensive management framework has been constructed in this paper, in order to do a systematic analysis on the approach of intellectual capital...
In this paper, we propose a video noise reduction method in low light environment. The basic idea is to analyze the pixel characteristic of the image. Divide the image into four kinds of regions and filtering these regions with different ways. The main advantage of the technique is that it is able to reduce the noise variance in smooth areas but at the same time retains the sharpness of edges in object...
The decentralized and anonymous characteristics of P2P environments make the task of controlling access to sharing information more difficult, which cannot be done by traditional access control methods. In this paper, the access control requirements in such environments were identified, and an access control model for P2P file-sharing systems based on trust and recommendation was proposed. The model...
