Compressive Stepped-Frequency Continuous-Wave Ground-Penetrating Radar
IEEE Geoscience and Remote Sensing Letters, 2010Data acquisition speed is an inherent problem of stepped-frequency continuous-wave (SFCW) radars, which may discourage further usage and development of this technology. We propose an emerging paradigm called compressed sensing (CS) to overcome this problem. In CS, a signal can be reconstructed exactly based on only a few samples below the Nyquist rate.

Continuous wave radar circuitry testing using OFDM technique
2014 IEEE 32nd VLSI Test Symposium (VTS), 2014Testing radar circuitry is challenging which requires characterizing system response over a set range of frequencies. In this research, we propose a method that can effectively leverage radar test speed with little design overhead. Currently radar circuitry is tested mainly through the functional test, where step frequency continuous wave (SFCW ...

Implementation of Frequency Modulated Continuous Wave Radar Altimeter
2016 Online International Conference on Green Engineering and Technologies (IC-GET), 2016EMI/EMC issues are the most important design challenges for modern electronic systems. The problem becomes quite complex in case of mixed signal processing. Traditional techniques for noise and interference reduction may not produce desirable solutions in such situations. Frequency Modulated Continuous Wave (FM-CW) Radar Altimeter required for altitude

A beam scanning frequency modulated continuous wave radar
IEEE Transactions on Instrumentation and Measurement, 1998This paper proposes the addition of a frequency scanning antenna to a conventional frequency modulated continuous wave radar with possible application to an anti-collision system in a vehicle. It is shown possible to extract the target range and angular position by analyzing the target echo in both time and frequency domains.

Calibration of the Self-Radar-Cross-Section of Continuous-Wave Radars
IEEE Transactions on Microwave Theory and TechniquesThis article presents a calibration method to eliminate measurement errors introduced by the own radar cross section (self-RCS) of continuous-wave (CW) radar systems, which focus on the measurement of relative target motions. By measuring the radar response of an unknown target located at known positions, the proposed procedure retrieves the ...

Continuous-Wave Doppler Radar for Human Gait Classification
2017Radar technology has commonly been used to estimate the speed and distance of a moving object. In recent years, it has been investigated as an alternative sensing modality for moving target classification. In contrast to optical imaging systems such as digital and infrared cameras, radars can work in all weather conditions and from a distance ...

An antenna system of a continuous wave radar
4th International Conference on Antenna Theory and Techniques (Cat. No.03EX699), 2004The given work describes an antenna system of continuous wave decimeter radar. The transmitting and receiving antennae are cylindrical spirals with the oppositely directed windings, where the distance between the axes is comparable with the wavelength. The main antenna parameters have been experimentally determined.

Continuous-wave radar sensor for structural displacement monitoring
2019Infrastructure systems are tied closely to the function of human society in many aspects. Effective approaches to maintaining infrastructure are critical for public safety. The assessment of structural conditions, diagnosis of structural damage, and infrastructure safety protection may be achieved by monitoring and analyzing structural responses.

Stepped Frequency Continuous Wave Ground Penetrating Radar applications
2016 9th International Kharkiv Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves (MSMW), 2016Ground Penetrating Radar (GPR) operating on the basis of Stepped Frequency Continuous Wave (SFCW) is analyzed for various applications with extraction of additional information about physical properties of soil and buried objects. The phase structure is obtained from the signal phase-frequency spectrum by applying the Discrete Fourier Transform (DFT ...
