Abstract

En fremgangsmåte for behandling av pulsede doppler-radarsignaler for å detektere et mål, innbefatter å sende ut radarsignaler fra et radarsystem i henhold til en forutbestemt frekvensteknikk, innbefattende signaler med frekvensdiversitet, å motta signaler innenfor et frekvensbånd innbefattende et målretursignal som har en frekvens om indikerer hastigheten til målet, og å transformere målretursignalet ved å bruke en Fourier-transformasjonen som har variabel frekvenskala.
