摘要

研究了扩展开槽波导天线工作频带的可能性。结果表明，通过使用传统的纵向槽和子阵列技术，可以达到约15%的相对带宽。这一结果通过一种用于高分辨率SAR应用的新型缝隙波导天线的开发得到了证明。天线工作在x波段，形成4°×6°波束，增益约30 dB。

A wideband slotted waveguide antenna for SAR systems

Possibilities for the extension of the operational frequency band of slotted waveguide antennas are studied. It is shown that by using both conventional longitudinal slots and subarraying techniques it is possible to reach the relative bandwidth of about 15%. This result is illustrated by the development of a novel slotted waveguide antenna for high-resolution SAR applications. The antenna operates in the X-band and forms the beam of 4°×6° with the gain of about 30 dB.
