Thermal-wave radar: a novel subsurface imaging modality with extended depth-resolution dynamic range.
نویسندگان
چکیده
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) instead of conventional PTR. A practical TWR image resolution augmentation method is proposed.

Truncated-correlation photothermal coherence tomography for deep subsurface analysis
Photothermal diffusion-wave imaging is a promising technique for the analysis of a range of media. However, traditional diffusion-wave techniques are limited by the physics of parabolic diffusion and can only produce depth-integrated planar images. Here, we report a depth-resolved photothermal imaging modality, henceforth termed truncated-correlation photothermal coherence tomography (TC-PCT). ...
متن کاملSimulation of radar sounder echo from lunar surface layer and detection of lunar subsurface structure
In lunar exploration, spaceborne high frequency (HF) radar sounder is an effective tool for investigation of lunar subsurface structure in lunar exploration [1] [2]. The primary strategy for radar sounder detection of subsurface structure is through the time delay and intensity difference of the lunar surface and subsurface nadir echoes (Figure 1). It is important to fully understand electromag...
متن کاملExtending the Radar Dynamic Range using Adaptive Pulse Compression
The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...
متن کاملPACS No: 41.20.Jb
Ground Penetrating Radar (GPR) is an imaging technique that uses wide-band nonsinusoidal electromagnetic waves to produce high-resolution images of the subsurface typically from 0-–10 m depth. GPR is an effective tool for subsurface inspection and quality control on engineering construction projects. The survey method is rapid, nondestructive and noninvasive. GPR has been successfully applied t...
متن کاملThree-dimensional Borehole Radar Imaging
Before embarking on any mining operation, it is advantageous to locate the subsurface orebody in three-dimensions with a high resolution (~1m) ahead of actual mining, because this will increase productivity and efficiency. Borehole radar is such an emerging mapping tool in the mining industry, that can be used to image the subsurface orebody with high resolution. 3-D subsurface imaging using tw...
