Asia-Pacific Symposium on Electromagnetic Compatibility (APEMC)

In high-speed electrical designs, the in-circuit characteristics of the components are usually obtained from in-circuit measurements as the references for designers. The two-probe approach (TPA) is one of in-circuit measurement approaches by adopting the inductive coupling effects of the current probes, and it gains good accuracy below 30MHz. In this paper, we propose an improved two-probe approach (ITPA) by introducing network parameters. Rather than modeling the measurement setup using equivalent circuits in the TPA, the proposed ITPA models it by using a three-port network, and pre-calibrates it before real measurements. By comparing the results measured from ITPA with those from the impedance analyzer (IA), it is proven that, the ITPA extends the highest measurement frequency to 100MHz from 30MHz (with the TPA), while maintaining allowable accuracy; besides, the ITPA avoids the trial-error pre-calibrations required in the TPA.

In this paper, a scheme of a large point FFT processor with configurable transform length is proposed. To achieve a pipelined structure, the proposed scheme is designed by Radix-2 decimation-in-frequency (DIF) FFT algorithm with Single-path Delay Feedback (SDF) architecture. A prototype is implemented on Xilinx Virtex-7 XC7VX690T FPGA, which can compute 16~128K FFT at a speed as high as *** scheme is superior to existing technologies, due to its ability to process a continuous-flow input sequence and its prospect for real-time, configurable transform length applications.

High range resolution of synthetic aperture radar (SAR) can be obtained by using the stepped-frequency technique, but it is still a problem how spectrum reconstruction methods can be combined correctly and effectively with SAR imaging algorithms. This paper analyzes the feasibilities of all the potential combinations between spectrum reconstruction methods and SAR imaging algorithms, and the optimal combinations are proposed. The simulation results verify the analysis in this paper.

The reduction of SAR image speckle noise is an important issue. However, the existing denoising methods may cause the resolution and details loss. This paper proposes a SAR image speckle reduction method based on the guided image filtering. This method combines the edge-preserving property of guided filtering and can maintain the detail information meanwhile suppressing the speckle. Experimental results show that the proposed method can effectively reduce speckle and keep the polarization information, point targets and texture structure. Meanwhile, it is able to handle large SAR images simply and effectively.

The radar systems have been so significant for both civil use and national defense, and adopting localized processor has become critical for a country, especially for the area related to the national defense. In this paper, we utilize localized BWDSP100 as the main processor, and implement a high-speed and real-time signal processing system by using BWDSP100 + FPGA framework. We use FPGA to realize the interface conversions and extensions, which enhance the reading bandwidth of the DDR2 interface from 235MB/s to 562MB/s. Besides that, we also integrate highspeed serial buses, such as PCIe interface of 243MB/s and SRIO interface of 344MB/s, for communications in or between boards. The system has been used in several projects, and works well.

This paper proposes a new SAR (Synthetic Aperture Radar image watershed segmentation method based on contextual statistical features analysis. This method firstly homogenizes all the sub-blocks of image by analysing statistical features, and then extracts the feature of each homogenized sub-block. Finally, the watershed area of this image can be segmented by means of Otsu algorithm. The experimental results show that our proposed method outperforms the conventional methods in both accuracy and time consuming.

This paper introduces an algorithm based on the context of MRF (Markov random field) model, and this method achieved oil spilling detection and segmentation. In this paper, the two important elements are initial labelling field and potential parameter estimation. The algorithm model chooses optical pyramid of saliency map as initial label field and Ising model as segmentation function. Using the GMM (Gaussian Mixture Model) and MAP (Maximum a Posterior) get local optimal result by ICM (Iteration Condition Model) method. This paper is also deeply researching the potential parameter which is the impact factor in segmentation function. Through studying the relationship between potential function and every scale-levels of saliency pyramid, the paper gets the better result which is more accuracy segmentations and keeping more texture information. The series experiments prove this method having false alarming rejection and noise suppression function in Oceanic SAR images.

Extracting the oil spills in SAR images has been challenged by the spatial heterogeneity caused by the speckles. In this paper, we present a novel variational formulation based on the local characteristics of SAR images for CV mode. The proposed method is aimed to solve the segmentation problem caused by SAR image speckles. Compared with the traditional CV model, the performance of the improved CV model is verified by plenty of real airborne SAR images and the experimental results on the real data show its efficiency and accuracy. By presenting various results in the classical threshold segmentation method and Markov random field method respectively, we conclude that the improved CV model is effective and accurate.

With the rapidly development of video satellites, which provide sequential remote sensing images, amounts of data with high quality information are hunted to disposition. Object detection is one of the useful applications for video satellite and we focus on plane detection in this paper. Previous object detection methods focus on spatial structure rather than temporal information because they handle single image instead of video. We introduce a P-N learning structure dedicated to sensing video, which is firstly adopted in remote sensing video multi-object detection. We adapt a temporal management as P-expert and adapt a unique cascade classifier as N-expert. Our method use both structure information and temporal information, which make it more effective for sensing video. We detail each module and present an experiment to show the validity.

Frequency Modulated Continuous Wave (FM-CW) waveform has been widely used in radar range measuring, speed measuring and imaging. However, the performance of matched filtering for range compression is usually degraded by the nonideal factors in the real radar system, such as the frequency modulation ratio error and the unstable sampling clock. In this paper, an iterative method is proposed to compensate these phase errors induced by the nonideal factors based on the entropy minimum. The principle of the proposed iteration is to construct a series of local quadratic curves to gradually approach the minimum. Finally, both simulated and experimental datasets are used to validate the feasibility and effectiveness of the proposed method.
