Signal peculiarities of autodyne systems of short-range radar at target vibrations
2014 20th International Conference on Microwaves, Radar and Wireless Communications (MIKON), 2014Research results on signal and noise characteristics of autodyne microwave vibration sensors are discussed for external feedback weak and strong. Also, questions are considered about selection of working points and ways of autodyne signal identification.

Methods of autodyne signal registration
13th International Crimean Conference Microwave and Telecommunication Technology, 2003. CriMiCo 2003., 2003In 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.

Analysis of Autodyne Signal from Distributed Reflecting Object
2007 17th International Crimean Conference - Microwave & Telecommunication Technology, 2007The autodyne signal features revealed for the radar environment model considered demonstrate that in the autodyne short-range radar with Doppler target selectivity it is necessary to take into consideration the presence of combinative signal interference from the separate reflecting objects.

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), 2020The 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.
