Verification of a Continuous Wave Noise Radar
2019 20th International Radar Symposium (IRS), 2019This paper discusses the importance of being able to verify the performance of all radars. It addresses the lack of published methods for the methodical verification of continuous wave radars. An outline is given of a systematic verification procedure for all types of modulated continuous wave radars, with particular regard to its applicability to ...

Stepped frequency continuous wave radar-data preprocessing
Proceedings of the 2nd International Workshop onAdvanced Ground Penetrating Radar, 2003., 2004Radar systems have been paid a lot of attention since the end of WWII. Along with performances improvement one has witnessed a diversification of their applications, which range from target detection and parameter measuring to navigation systems, anti-collision systems and subsurface sensing.

Tracking driver's heart rate by continuous-wave Doppler radar
2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016Developing driving safety system with medical assistance devices for preventing accidents has become a major social issue in recent year. These devices have been developed using electrocardiogram (ECG) and photoplethysmogram (PPG) for measuring the heart rate (HR). However, driver should directly contact with the sensor for monitoring the HR. Recently,

Frequency Modulated Continuous Wave Radar
2013The need to see without being seen has been the cardinal principle of military commanders since the inception of warfare. Until the advent of World War II, the only means available to commanders from this point of view was espionage and intelligence gathering missions behind enemy lines.

A radar system transmits EM waves and receives them upon scattering from a target. The extent of the information about the target derived by the radar depends on the transmitted and received waveform parameters, i.e., amplitude, frequency, and phase, and on the vector nature of EM waves, i.e., polarization.

Basic gait analysis based on continuous wave radar
Gait & Posture, 2012A gait analysis method based on continuous wave (CW) radar is proposed in this paper. Time-frequency analysis is used to analyze the radar micro-Doppler echo from walking humans, and the relationships between the time-frequency spectrogram and human biological gait are discussed.

Frequency Modulated Continuous Wave Radar for Range Detection
2018 18th Mediterranean Microwave Symposium (MMS), 2018In this paper, a Frequency Modulated Continuous Wave Radar is built using radio frequency techniques. Radar can measure the nearest object's range from 2 to 30 meters with 1-meter range resolution. The design process was carried out by using computer-aided design techniques, and mathematical tools. The hardware prototype was built and measurements were

Holographic techniques in continuous wave bistatic radars
Proceedings of the IEEE, 1970Continuous wave bistatic radars provide information on moving targets. This letter observes that because such targets usually generate signals at the receiver which closely approximate a zone plate pattern, hologram procedures, i.e., synthetic aperture radar procedures, can offer a significant improvement in the signal-to-noise ratio in such radars.
