IEEE transactions on microwave theory and techniques, 2019
This article proposes a single-conversion stepped-frequency continuous-wave (SCSFCW) radar that combines a stepped-frequency continuous-wave (SFCW) radar and a self-injection-locked (SIL) radar to benefit from the range resolution and the Doppler ...

Frequency modulated continuous wave ultrasonic radar
2013 18th International Conference on Digital Signal Processing (DSP), 2013Pulse compression techniques relying on chirp excitation are largely adopted in both diagnostic and Non-Destructive Testing applications for ultrasound. In the present work, the adoption of the Frequency Modulated Continuous Wave Radar technique to ultrasonic Non-Destructive Testing is considered.

Experimental Frequency Modulated Continuous Wave radar
2015 16th International Radar Symposium (IRS), 2015In this article we focused on description and practical experience of our work. It was based on development and construction of experimental and simply reconfigurable Frequency Modulated Continuous Wave (FMCW) radar. Found solution allows quick modification of the system parameters as well as parameters of transmitted and received signals ...

Contactless Carotid Pulse Measurement Using Continuous Wave Radar
2018 Asia-Pacific Microwave Conference (APMC), 2018Cardiovascular diseases are one of the major causes of death. Regular checkups and preventive actions can drastically help reducing fatal incidences. This can be achieved by monitoring the carotid artery or rather the carotid pulse signal. Commonly, ultrasound devices are used for that purpose.

Continuous-wave software-defined radar interferometry
Advanced Topics in Optoelectronics, Microelectronics and Nanotechnologies X, 2020This paper presents an experimental implementation of continuous-wave interferometric radar based on low cost USRP platform and computer. The purpose of the proposed system is to measure small displacements of the monitored target over a long time period. These measurements are extremely useful in the field of civil engineering. Common applications are
