Traditional micro-Doppler (m-D) analysis theories largely focus on isolated targets, making these theories difficult to utilize in monitoring and recognizing space group targets. This letter proposes an algorithm for separating ballistic group targets based on the extraction of micromotion features. Modeling the ballistic targets as cone–cylinder models, the skeleton extraction method in morphology...
Bistatic radar is gaining more and more interest by the radar community over the last years, and Micro-Doppler information is regarded to be the unique features of radar's targets. In this paper, a geometric of bistatic radar and vibrating target is constructed. Then in bistatic radar system, the Micro-Doppler information reduced by vibrating structure of target is analysis via Gabor-Transform. Then...
In this paper, we combine GRA (grey relation analysis) with fuzzy TOPSIS to evaluate performance of iron and steel companies. In the empirical study of a Chinese iron and steel company, we apply grey relation analysis to find representative indices. Then fuzzy TOPSIS is utilized to evaluate the value creation strategy performance of the company. By the evaluation, we can get the conclusion that the...
Nowadays, with the development of silicon fabrication technology from 130 um technology in early 70's till present 45 nm technology, the geometries of transistors shrink smaller and smaller, IC devices become more sensitive to electrostatic discharge, or electrical overstress, i.e. ESD/EOS. ESD/EOS, therefore, is one of the major causes of device failures in the semiconductor industry. Tremendous...
For the problem of low code gain of the concatenation of Reed Solomon (RS) codes and convolutional codes (CC), the concatenated scheme of RS+CC and Luby transform (LT) codes with an improved decoding algorithm is proposed. The improved decoding algorithm for LT codes decreases the receiving buffer consumption and improves the successful decoding probability and the real-time property of LT codes at...
