Abstract

The Advanced Synthetic Aperture Radar (ASAR) is a major instrument on board ENVISAT-1. The next Earth observation mission of the European Space Agency. It will represent a sensor of paramount importance for the remote sensing community because of its enhanced flexibility with respect to the existing SARs in the AMI on board ERS-1 and ERS-2. The unique combination of different spatial resolutions, incidence angles, swath width sizes and polarisation diversity will offer an increased number of operational modes tailored for a large set of scientific and operational applications. Among the innovative design features of this radar are the use of an active antenna concept for tailoring the transmit and receive elevation beams to different mode geometries, a digital generation waveform technique for obtaining variable time-bandwidth products and a block adaptive quantization compression scheme. In this paper, the ASAR antenna is described and the development status is presented.

欧空局突破性合成孔径雷达:ENVISAT-1 ASAR有源天线

先进合成孔径雷达(ASAR)是ENVISAT-1上的主要仪器。欧洲航天局的下一个地球观测任务。它将成为遥感界最重要的传感器，因为它相对于ERS-1和ERS-2上AMI中现有的sar增强了灵活性。不同空间分辨率、入射角、条带宽度大小和偏振多样性的独特组合将为大量科学和操作应用提供更多的操作模式。该雷达的创新设计特点包括使用有源天线概念来定制发射和接收仰角波束以适应不同的模式几何形状，用于获得可变时间带宽产品的数字生成波形技术和块自适应量化压缩方案。本文对ASAR天线进行了介绍，并介绍了其发展现状。
