Frequency Deviation of Injection-Locked Microwave Autodynes
MetadataShow full item record
This article presents the results of the autodyne (AD) frequency deviation research, which is simultaneously affected by its own reflected radiation and the external synchronisation signal. The basic correlations are obtained for the injection-locked AD (ILAD) analysis in the case of a moving radar object. The amplitude-frequency characteristics are calculated for the transfer coefficient of the autodyne phase variations and the ILAD frequency deviation. The advantages of ILAD are shown compared to AD without synchronisation. The theoretical research investigations are confirmed by experimental data obtained by the example of an oscillator made on the basis of the 8-mm Gunn diode.
