▁Division ▁plant ▁of ▁R CA ▁in ▁Mo or est own , ▁New ▁Jersey . ▁The ▁C - band , ▁low - power , ▁cross - section - measure ment ▁system ▁in ▁conj unction ▁with ▁two ▁static ▁range ▁configurations ▁was ▁used ▁for ▁full - scale ▁targets ▁we igh ing ▁up ▁to ▁ 4 , 0 0 0 ▁pounds ▁rot ated ▁through ▁ 3 6 0 ▁degrees . ▁Since ▁measurements ▁must ▁be ▁made ▁on ▁targets ▁as ▁if ▁they ▁were ▁located ▁in ▁free ▁space , ▁returns ▁from ▁other ▁than ▁the ▁target ▁were ▁reduced ▁to ▁ 1 0 − 5 ▁m ², ▁the ▁general ▁background ▁level ▁of ▁one ▁tower - ter rain ▁combination . ▁The ▁low - power ▁rad ar ▁was ▁capable ▁of ▁transm itting ▁any ▁linear , ▁circular , ▁or ▁elli pt ical ▁polar ization ▁at ▁C - band ▁frequencies . ▁It ▁could ▁receive ▁the ▁horizontal ▁and ▁vertical ▁components ▁of ▁back sc atter ed ▁energy ▁simultaneously . ▁Cross - section ▁data ▁was ▁recorded ▁in ▁analog ▁form ▁on ▁San born ▁and ▁Scient ific ▁Atlanta ▁strip - chart ▁record ers ▁and ▁on ▁Am pe x ▁magnetic ▁t ape . ▁Digital ▁cross ▁sections ▁were ▁also ▁recorded ▁on ▁a ▁spe cially - des igned ▁C EC ▁magnetic ▁t ape ▁rec order . ▁ ▁Other ▁important ▁functions ▁of ▁the ▁E RL ▁were ▁the ▁training ▁of ▁technical ▁personnel , ▁development ▁and ▁checkout ▁of ▁new ▁equipment ▁and ▁techniques , ▁and ▁satellite ▁tracking ▁using ▁a ▁modified ▁F P Q - 4 ▁rad ar . ▁L - band ▁measurement ▁cap ability , ▁similar ▁to ▁the
