dc.description.abstractTo increase the image quality of synthetic aperture radar (SAR) is one of the hot issues for high-performance detection/reconnaissance. With this interest in the SAR technique, it generates various techniques according to the purposed platforms (Auto-SAR, ViSAR, InSAR, and PolSAR). In this article, we introduce high-efficiency and useful techniques, which can be applied to various SAR applications for generating high-quality images in the Ka -band. We proposed the stretched deramping hardware system applicable in the Ka -band, and design the Range-Doppler algorithm which well matches the proposed radar system with the modified signal parameters. Thus, we can extend the integration time of the convolution process in slow time and it leads to the improvement of the SAR image quality. To verify the performance of our proposed technique, we process the practical experiments in conventional outdoor fields. Furthermore, the proposed method is operated on the range Doppler algorithm (RDA), which is mostly used for standard SAR.-
