On Wave Radar Measurement
The SAAB REX WaveRadar sensor is widely-used for platform-based wave measurement systems by the offshore oil and gas industry. It offers in-situ surface elevation wave measurements at relatively low operational costs. Furthermore, there is adequate flexibility in sampling rates, allowing in principle sampling frequencies from 1 Hz to 10 Hz, but with an angular microwave beam width of 10 degrees...
متن کاملTerahertz Imaging, Millimeter-wave Radar
The millimeter wave (MMW) band of frequencies extends from 30 GHz to 300 GHz, with some fuzziness on both ends of this spectrum. The terahertz (THz) band extends from about 200 GHz to about 30 THz, despite the fact that the lower frequencies in this range are not strictly 10 Hz or higher. These bands are also variously called submillimeter, far-infrared, and near-millimeter. In recent years, th...
متن کاملThermal-wave radar: a novel subsurface imaging modality with extended depth-resolution dynamic range.
Combining the ideas behind linear frequency modulated continuous wave radars and frequency domain photothermal radiometry (PTR), a novel PTR method is introduced. Analytical solutions to the heat diffusion problem for both opaque and transparent solids are provided. Simulations and experimental results suggest a significant improvement in the dynamic range when using the thermal-wave radar (TWR...
متن کاملMillimeter-Wave Radar Technology for Automotive Application
Mitsubishi Electric Corporation has developed a millimeter-wave radar for automotive application. Monolithic microwave integrated circuits (MMICs), developed specifically for this application by Mitsubishi Electric, are used for the radio-frequency (RF) module to obtain outstanding radar performance. This millimeter-wave radar incorporates a signal-processing unit in the radar head, resulting i...
متن کاملS-Band Doppler Wave Radar System
In this paper, a novel shore-based S-band microwave Doppler coherent wave radar (Microwave Ocean Remote SEnsor (MORSE)) is designed to improve wave measurements. Marine radars, which operate in the X band, have been widely used for ocean monitoring because of their low cost, small size and flexibility. However, because of the non-coherent measurements and strong absorption of X-band radio waves...
