Ob Qhov Tseem Ceeb Txuj Ci Zoo Ntawm Fm Cw Radar Qib Meter

Muaj ob hom tseem ceeb ntawm radar qib transmitters ntawm lub khw. Ib qho yog high-frequency radar qib ntsuas, uas nws kis tau tus mob yog feem ntau nyob rau hauv ntau ntawm 24 mus rau 26 GHz. Lwm tus yog afm qw radarqib 'meter', nws zaus feem ntau yog siab dua 78 GHz lossis 80 GHz. Qhov zaus-modulated nruam nthwv dej radar qib ntsuas muaj ob yam tseem ceeb. Cia wb mus saib lawv ua ke.

1. Muaj peev xwm ua kom pom tseeb. Transmission angle ntawm lubfm qw radartheem 'meter' yog ncaj qha ntsig txog qhov ceev ntawm lub teeb, qhov ua tau zoo ntawm thaj tsam ntawm lub kav hlau txais xov, thiab qhov zaus. Raws li cov xwm txheej ib txwm muaj, nyob rau hauv qhov kev pom zoo tias thaj chaw hla ntawm lub kav hlau txais xov tseem tsis hloov pauv, qhov siab dua qhov kis tau tus mob, qhov tsawg dua qhov kis tau tus mob, thiab rov ua dua. Yog li ntawd, qhov me me ntawm lub kaum sab xis ntawm qhov zaus-modulated nruam nthwv dej radar qib ntsuas, qhov muaj peev xwm ua kom pom tseeb dua, qhov muaj zog ntawm lub ncha teeb liab, thiab qhov ntsuas qhov tseeb ntau dua. Nyob rau hauv sib piv, qhov zaus-modulated nruam nthwv dej radar theem meter muaj ib tug muaj zog focusing peev xwm thiab ib tug ruaj khov ncha teeb liab.

2. Dav ntau yam dynamic. Lub dynamic ntau yog hais txog qhov sib txawv ntawm qhov muaj zog ncha teeb liab thiab qhov tsis muaj zog ncha teeb liab pom los ntawmfm qw radarqib meter. Feem ntau hais lus, dynamic ntau yam ntawm high-frequency radar theem meter yog nyob ib ncig ntawm 96dB, thaum lub dynamic ntau yam ntawm 80 GHz radar theem transmitter tuaj yeem ncav cuag 120dB. Qhov loj ntawm qhov dynamic ntau yam qhia txog radar qib meter lub peev xwm los kuaj xyuas lub zog ntawm lub teeb liab, uas yog, qhov loj dua qhov dynamic ntau, lub peev xwm muaj peev xwm los ntes cov cim tsis muaj zog. Txij li thaum lub radar nthwv dej emissions los ntawm radar qib meter raug cuam tshuam los ntawm dielectric qhov nruab nrab, qhov loj dua qhov dielectric tas li, lub zog ncha teeb liab. High-frequency radar theem ntsuas muaj qhov ntsuas zoo dua ntawm kev tshaj tawm nrog lub dielectric tas li ntau dua 2, thaumfm qw radarqib ntsuas ntsuas tau cov xov xwm nrog lub dielectric tas li ntau dua 1.1.
