主星帶小衛(wèi)星分布式SAR干涉的相對(duì)測(cè)高精度分析

Analysis of Relative Height Accuracy for Master Satellite and Distributed Small Satellite SAR Interferometry

  • 摘要: 相對(duì)測(cè)高精度是干涉SAR測(cè)高性能的重要指標(biāo)之一。該文根據(jù)主星帶小衛(wèi)星分布式SAR系統(tǒng)的實(shí)際空間幾何條件下建立了干涉測(cè)高原理;基于相對(duì)測(cè)高幾何,推導(dǎo)了相對(duì)測(cè)高精度與干涉相位誤差的關(guān)系式;理論分析了基線去相關(guān)、圖像配準(zhǔn)誤差去相關(guān)、熱噪聲去相關(guān)等,并推導(dǎo)了圖像相關(guān)系數(shù);最后,仿真分析了圖像去相關(guān)因素對(duì)于主星帶小衛(wèi)星分布式SAR干涉的相對(duì)測(cè)高精度影響。結(jié)果發(fā)現(xiàn):對(duì)于平坦地形來(lái)說(shuō),熱噪聲與配準(zhǔn)誤差是影響相對(duì)測(cè)高精度的主要因素,而基線去相關(guān)影響相對(duì)較小。
