In the paper we will explain the details of the proposed frequency scanning technique, model the antenna and corresponding SAR performance, and provide examples of affordable multi-mode …

Whilst the displaced phase center technique aims at improved azimuth resolution at reduced PRF the multiple phase centers in elevation aim at improved signal to noise by using the high gain …

该数据集包含了覆盖中国不同区域的27景高分三号（GF-3）精细模式SAR图像，并从中获取了建筑区共计60000个SAR样本数据，结合光学图像与专家解译，制作了与样本数据对应的标签图像 …

2024年9月14日 · Azimuth resolution and swath width are two crucial parameters in spaceborne synthetic aperture radar (SAR) systems. However, it is difficult for conventional spaceborne …

We investigate SAR performance and processing of sparse, multiple-aperture arrays. Three filters are evaluated: the matched filter, maximum-likelihood filter, and minimum mean-square error …

2023年6月23日 · The detection of vehicle targets in wide-area Synthetic Aperture Radar (SAR) images is crucial for real-time reconnaissance tasks and the widespread application of remote …

2023年11月24日 · In this article, we propose a novel method that parameterizes the time-varying area observed by the spaceborne SAR operating in the boresight stripmap mode into a fixed …

2023年9月1日 · Synthetic Aperture Radar (SAR) data are useful for BA mapping due to strong coherent backscatter from diverse human-made targets, distinct texture patterns, and …

Today, synthetic aperture radar (SAR) plays an important role in military ground surveillance and earth observation. Since the late eighties a couple of SAR-systems have been developed for …

2017年7月1日 · In this article, a novel 2-D scanning synthetic aperture radar mode for high-resolution and wide-swath imaging is introduced. Instead of the interpulse progressive azimuth …
