摘要

充气技术已被确定为解决未来NASA星载合成孔径雷达(SAR)天线实现小质量、高封装效率和可靠部署问题的潜在解决方案。目前,双极化l波段SAR天线的孔径尺寸为10 m/spl倍/3 m,中心频率为1.25 GHz,带宽为80 MHz,具有电子束扫描功能,质量小于100 kg。所展示的工作是开发这种充气天线阵列的持续努力的一部分。

A dual-polarized microstrip subarray antenna for an inflatable L-band synthetic aperture radar
Inflatable technology has been identified as a potential solution to the problem of achieving small mass, high packaging efficiency, and reliable deployment for future NASA spaceborne synthetic aperture radar (SAR) antennas. Presently, there exists a requirement for a dual-polarized L-band SAR antenna with an aperture size of 10 m/spl times/3 m, a center frequency of 1.25 GHz, a bandwidth of 80 MHz, electronic beam scanning, and a mass of less than 100 kg. The work presented is part of the ongoing effort to develop such an inflatable antenna array.
