摘要
Abstract
The impact of rain attenuation and depolarization on the performance of LEO satellite X-band data transmission link with dual-circular polarization are analyzed. Base on a bit error rate threshold requirement, the cross-polarization interference caused by depolarization may be regarded as AGWN. The XPD requirements of the X-band remote sensing satellite data receive system are proposed. The results have been used in the design of the data receiving system for the double-circular polarized re-mote sensing satellite. The data from ZY-3 satellite (dual circular polarization frequency reuse remote sensing satellite, whose data rate is 450Mbps×2) was successfully received.关键词
