Abstract

Foreliggende oppfinnelse er relatert til feltet med elektromagnetiske deteksjonssystemer som opererer i bistatisk modus, særlig til UHF/VHF bistatiske radarer. Fremgangsmåte i henhold til foreliggende oppfinnelse består av samtidig bruk av signaler sendt fra en eller flere sendende kilder på separate frekvenskanaler. Fremgangsmåten innbefatter særlig: - et trinn for multikanalmottak og å separere kanaler, - et trinn for å analysere signalene mottatt kanal for kanal, der analysen blir utført ved korrelasjon av signalene mottatt med kopier av tid og frekvensforskjøvne referansesignaler, referansesignalet er dannet av signalene mottatt fra sendende kilder ved direktesending, - et trinn for integrasjon av signalene som blir analysert, kanal for kanal, - et trinn med deteksjon. Fremgangsmåten i henhold til foreliggende oppfinnelse muliggjør et signal å bli brukt hvis båndbredde er lik med båndene dekket av settet av kanaler som blir brukt, som forbedrer kontrasten og avstandsoppløsningen i systemet som implementerer fremgangsmåten sammenliknet med systemet i den kjente teknikk.
