Methods of autodyne signal registration

Abstract

In order to increase autodyne radar sensibility and its reach, accordingly, it is proposed to record autodyne frequency changes. At the moving of reflecting object, oscillations occur with Doppler frequency. Autodyne system becomes cheaper and less complicated if autodyne signal is recorded in the feed circuit. For this purpose resistors, chokes and transformers are used. From the analysis conducted it follows, that autodyne radar, which records the change of oscillation frequency is close to potential limit of autodyne systems.
