摘要
商用自组装(COTS)组件最近在合成孔径雷达(SAR)应用中得到了广泛的应用。这些设备的计算能力已经发展到可以实时处理复杂SAR算法的水平。本文以德州仪器公司的一款低功耗多核数字信号处理器(DSP)为研究对象，对其SAR信号处理能力进行了评估。这里研究的具体DSP是一个代号为TMS320C6678的八核器件，仅为10瓦提供128 GFLOPS(单精度)的峰值性能。我们描述了如何在这样的设备中有效地实现基本的SAR操作。我们的研究结果表明，基线SAR距离-多普勒算法对于16 M (4K × 4K)图像大约需要0.25秒，实现了实时性能。
Synthetic Aperture Radar on low power multi-core Digital Signal Processor
Commercial off-the-self (COTS) components have recently gained popularity in Synthetic Aperture Radar (SAR) applications. The compute capabilities of these devices have advanced to a level where real time processing of complex SAR algorithms have become feasible. In this paper, we focus on a low power multi-core Digital Signal Processor (DSP) from Texas Instruments Inc. and evaluate its capability for SAR signal processing. The specific DSP studied here is an eight-core device, codenamed TMS320C6678, that provides a peak performance of 128 GFLOPS (single precision) for only 10 watts. We describe how the basic SAR operations can be implemented efficiently in such a device. Our results indicate that a baseline SAR range-Doppler algorithm takes around 0.25 second for a 16 M (4K × 4K) image, achieving real-time performance.
