Data-recording device for aircraft requires high-speed, high-capacity and non-volatile storage. In the paper, we provide a good solution for high-speed large-capacity data logger. We use FPGA as controller, SDRAM as high-speed data buffer, CF card as a non-volatile data memory and USB2.0 as Communication interface to design a dual-channel data logger. The Test results show that the recorder sampling rate is 120MSa/s, single-channel data store rate is 38MB/s, the total capacity is 64GB, and data upload rate is up to 30MB/s. Therefore it meets the expectations.
To avoid falling into local optimum solution and improve global optimum efficiency and accuracy of particle swarm optimization, a novel particle swarm optimization model with centroid of population is proposed, which ...

Image fusion has been one of the main technical routines used to detect and recognize objects from images. Loss of information is unavoidable in fusion process. So it is very important contents of image fusion how to avoid the loss of useful information or how to preserve features which are helpful to the detection. In consideration of these issues and the fact that most detection problems are actually to distinguish man-made objects from natural background, a fractal-based multi-spectral fusion algorithm has been developed. Source images are firstly orthogonally decomposed according to wavelet transform theories, then fractal-based detection is held to each decomposed image. After the district containing man-made objects is detected, a special composing operator is adopted to reduce the information loss of man-made objects. This fractal-based algorithm is compared with a common weighted average fusion algorithm and the experimental results imply that the fractal-based multi-spectral fusion algorithm can effectively preserve the information of man-made objects with a high contrast.
