Tsis ntev los no, National Space Administration (NASA) tau tshaj tawm tias Tuam Tshoj tau ua tiav lub ntiaj teb thawj lub ntiaj teb cov kab hluav taws xob hluav taws xob siab dav dav dav dav (SAR) satellite, Kev Tshawb Fawb Av No. 4 01 satellite. Lub voj voog loj hluavtaws aperture radar kav hlau txais xov tau ua tiav tiav, thiab lub satellite tau raug muab tso rau hauv kev ua haujlwm. Raws li lub ntiaj teb thawj lub ntiaj teb high-orbit SAR satellite nkag mus rau theem kev ua haujlwm ntawm engineering, Kev Tshawb Fawb Av No. 4 01 satellite "sawv siab thiab pom dav", nrog rau thaj tsam ib puag ncig ntawm ze li 1/6 ntawm Tuam Tshoj. Nws kuj yuav siv sij hawm rau hauv tus account ob hom kev suav pej xeem thiab hom zoo. Ntxiv rau qhov pom dav, ua tib zoo, thiab ntsia, nws tseem tuaj yeem ua tiav sai, kev daws teeb meem siab dua, thiab "me me thiab meej" saib, suav nrog ntau qhov xwm txheej kub ntxhov, Nws hom kev kub ntxhov tuaj yeem txhawb kev saib xyuas cov kev xav tau hauv cov xwm txheej uas muaj ntau yam kev puas tsuaj tshwm sim ib txhij. .
Txhawm rau kom cov satellites siab-orbit pom dav, zoo, nrawm, thiab meej meej hauv lub ntiaj teb loj, kev tsim cov kav hlau txais xov satellite yog qhov tseem ceeb. Kav hlau txais xov yuav tsum tsis tsuas yog ua tau raws li qhov yuav tsum tau ntawm lub teeb yuag, yooj yim satellite nqa thiab tso tawm, tab sis kuj tseem muaj lub aperture loj kom tau raws li cov kev xav tau ntawm lub teeb liab, thiab tseem muaj qee lub zog los xyuas kom meej lub satellite "siv" nyob rau hauv qhov chaw hnyav.
Nws tau tshaj tawm tias "micro tension" weaving thev naus laus zis rau cov hlau zoo heev monofilament mesh fabrics, tsim kho tshiab los ntawm xib fwb Chen Nanliang pab neeg los ntawm Tsev Kawm Ntawv ntawm Textile ntawm Donghua University, tso tseg cov kev xav ib txwm siv ntawm weaving mesh warp knitted fabrics thiab tsim kho tshiab. cov cuab yeej tshiab thiab cov cuab yeej siv rau kev xaws "micro tension" warp knitted mesh fabrics, zoo heev txo qhov hnyav ntawm lub kav hlau txais xov tshiab reflector thiab tsim ib lub voj voog loj loj nrog thaj tsam ze rau thaj tsam ntawm lub tsev hais plaub basketball, zoo heev txhim kho lub deployable antenna reflector cheeb tsam thiab Kev sib txuas lus muaj peev xwm ntawm siab orbit satellites.
