Passive radar has recently received attention due to its advantages like low cost, covert operation, and difficulty of jamming. With cognition ability added in, passive radar's performance can improve for its adaptability to the environment. In this paper, multi-illuminator compatible cognitive passive radar, which aims at future complex electromagnetic environment and best potential illuminators...
As lots of cities are facing a new baby boom in China and rural areas are facing a serious shortage of medical resources, China's maternal and child health care system is facing a lot of problems. In this paper we introduce an intelligent information system for maternal and child health care based on Body area networks and Cloud computing technologies. Wearable sensors are used for detecting physical...
In this paper, a frame of guided weapon with network has been proposed, the pitching loop, yawing loop and rolling loop share the network resource by time-division. To maximum the overall performance of the three control loops, an intelligent feedback scheduler is designed to allocate available network resource dynamically according to the limited network bandwidth and variable workload. The scheduler...
The inside and outside surfaces of the industrial pipe network could engender the oxidation layer by corrosion because of long-term operation. This could even put industrial production and human safety into a potential threat. So the non-destructive inspection of the metal thickness of pipe networks and the deduction of the erosive distribution of the inference wall is of great significance. However,...
In this study, a suboptimal controller for the pitch plane motion of a flexible launch vehicle is presented. Three sensors for measuring the motion, angular position sensor, angular rate sensor and accelerometer, are considered and assumed to be at given positions on a rocket described by a ninth-order state-space dynamical model, including three bending modes. The weighting matrices with respect...
Because of the features of remote sensing data such as large quantity, complex format and wide distribution in heterogeneous storage devices of different geographic locations, it is quite difficult for integrating, exchanging and sharing remote sensing data effectively. On one hand, it is very hard to get continuous remote sensing data for some research institutions and individuals who urgently need...
On the base of studying and analyzing the Globus Toolkit2.4 platform and remote sensing technology, this article uses the grid platform Globus Toolkit2.4 and the mode of parallel processing, develops a method of geometric correction for processing remote sensing images based on grid. It provides an approach for solving problems caused by RS imagepsilas characteristics of complexity and time consuming.
Efficient coverage area and efficient coverage area ratio of node are put forward by analysis of coverage problem of wireless sensor networks (WSN). It is theoretically proved through math modeling, theoretical analysis and formula deducting that how much the maximum efficient coverage area, the maximum efficient coverage area ratio, the maximum of net efficient coverage area and the maximum of net...
Multi-path effect is the main error source for GPS high precision positioning in near distance differential circumstance. This paper presents a novel method for vehicle navigation in the situation. The current state vector of a vehicle can be used to estimate the state vector in the next interval. Then residual error vector can be computed by using the estimated state vector and the state vector measured...
