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.

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 presents a novel extended multi-structure local binary pattern (EMSLBP) approach for high-resolution image classification, generalizing the well-known local binary pattern (LBP) approach. In the proposed EMSLBP approach, three-coupled descriptors with multi-structure sampling are proposed to extract complementary features (pixel value and radial difference) from local image patches. The anisotropic features derived from elliptical sampling are also rotation invariant by averaging the histograms over rotational angles and combined with the isotropic features extracted from circular sampling. Experimental results show that the proposed method can effectively capture local spatial pattern and local contrast, consistently outperforming several state-of-the-art classification algorithms.

In high-speed electrical systems, power distribution network (PDN) with power ground planes (PGP) is widely used to gain effective high-speed decoupling. Rather than modelling such PDN from conventional steady-state analysis in the frequency domain, we propose its two-dimension (2-D) charge delivery model from charge delivery perspective in the time domain, which correlates better with the PDN real operations. With the model, by taking the synthesized effects from the interactions of the charge providers (such as voltage regulator module (VRM) and capacitors) into account, we propose two design rules to optimize the placement of the capacitors in preliminary PDN design.

We are going to develop a handheld wall penetrating SAR (WPSAR) to investigate the small shallowly buried objects such as thin wires, cables and so on. The WPSAR will be working very close to the wall surface, and the objects of interest sometimes buried inside the induced near-filed region of the probe. As a result, the traditional far-field SAR imaging algorithm cannot be used. Thus, a useful near-field back-projection algorithm is investigated in this paper, which backprojects the probe's aperture field into the wall, instead of backprojecting the echo signal along the wave propagation track as it is done in the traditional BP. A full wave simulation data given by CST is used to validate our algorithm. The result shows that the proposed near-field BP algorithm gives a correct imaging result while the traditional one fails.

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.

Doppler Frequency Rate (FDR) is an essential parameter in the procedure of Synthetic Aperture Radar (SAR) processing. In this paper, we investigate an achievable autofocus algorithm, shift-and-correlate (SAC), and design the implementation of FDR estimation. The proposed method can dramatically improve the accuracy of imaging and reduce the time delay of the SAR imaging process. Depth-of-focus theory and linear fitting theory are discussed in this paper for decreasing the computation-consumption and the preserving precision. We verify the proposed method in a 16384*16384 SAR imaging process at 100 MHz system clock on a dedicated designed Field Programmable Gate Array (FPGA) tested. To testify the feasibility of the proposed method, we compared our run-out results with existing implementations using traditional DSP and MATLAB methods in terms of real-time performance and imaging quality.

This paper presents a use of multi-core DSP TMS320C6678 for the squinted-looking synthetic aperture radars (SARs) real-time signal processing method. This paper first briefly introduces the squinted-looking SAR algorithm and analyzes the signal processing by use of spectral analysis (SPECAN). Then, according to the requirement of squinted-looking SAR real-time imaging system, the high performance TI multi-core DSP TMS320C6678 is used for realizing the imaging algorithm through the virtual single-node technology for data transmission and interaction and the parallel approach to data processing. Finally, the flight experiment is carried out and the results show that the virtual processing method meets the requirements of the real-time imaging based on the multi-core DSP hardware platform effectively.

In this paper, we focus on the widely-used radix-2 2 Decimation-In-Frequency (DIF) Fast Fourier Transform (FFT) algorithm. A variable-length, controllable-precision FFT processor is proposed. The processor can perform 16, 64, 256 and 1024 point FFT/IFFT and provide flexible wordlength scaling modes for different FFT stages. Thus, the processor is suitable for different precision and FFT length requirements in various applications. Aiming at high throughput performance, single-path delay feedback (SDF) pipeline architecture is adopted. The design is testified on Xilinx Virtex6 xc6vcx240t FPGA. Accordingly, we make a clear comparison between the proposed design and Xilinx FFT v7.1. Our design achieves better signal-to-quantizationnoise ratio (SQNR) property and shorter pipeline latency. Meanwhile, the occupied resource is approximately the same. Moreover, SQNR performance of different FFT length and wordlength scaling modes is analysed.

Different azimuth targets have different Doppler centroid and different time support domain in slide spotlight synthetic aperture radar. Thus, it is hard to weighting window on the echo in slide spotlight mode. This paper proposed an azimuth weighting method of slide spotlight SAR based on subaperture chirp scaling algorithm. Firstly, the subaperture number of the algorithm is discussed based on the shift of Doppler centroid and the pulse repetition frequency(PRF). Secondly, the range cell migration and the remove of the azimuth phase of each subaperture are processed by chirp scaling algorithm independently. At last, the data of each subaperture is combined together, and the azimuth weighting window is applied after an azimuth de-ramp process of the combined data. The computer simulations verify the validity of the proposed algorithm.
