Resum

Aquesta carta investiga la possibilitat d'utilitzar geometries deliberades per a objectius rotatius, que poden millorar la detectabilitat i classificació mitjançant la seva signatura micro-Doppler. A més de la signatura proporcionada per la velocitat de rotació de l'objectiu, cada geometria particular condueix a formes d'ona moduladores específiques i úniques que augmenten la informació relacionada amb aquest objectiu. S'han dissenyat diferents rodes en forma d'estrella amb geometries particulars demostrant diferents característiques de reflexió i formes d'ona moduladora. La signatura d'aquestes rodes rotatives en forma d'estrella s'ha mesurat en una càmera anecoica utilitzant una plataforma de radar d'ona contínua (FMCW) de 24 GHz amb freqüència modulada per a ús general i un algorisme de detecció basat en la derivada de la correlació creuada es proposa per validar l'enfocament proposat.
