Calculation of Signal and Noise Characteristics of an Autodyne at the High Speed of Targets Motion

2020 Ural Symposium on Biomedical Engineering, Radioelectronics and Information Technology (USBEREIT), 2020
The paper presents the results of calculating the signal and noise characteristics of an autodyne for the general case of arbitrary values of the distance to the target and its speed. This is equivalent to an arbitrary ratio of the delay time of the reflected radiation and the period of the autodyne signal.

EHF autodyne signals for tracking the parameters of moving objects

Russian Physics Journal, 2000
To improve the characteristics of short-range autodyne radar systems and to extend their application range, it is very important from both theoretical and practical viewpoints to study the autodyne signal waveform and spectrum. In the present paper, the results of investigations into the specific features of the autodyne response of an EHF generator ...
