Three-dimensional Characteristics of Polarimetric Radar Variables
Understanding the characteristics of cloud microphysics in precipitation is important to enable accurate rainfall estimation through space-borne radar and microwave radiometers on satellites (e.g., TRMM, GPM, and AMSR-E) (e.g., Masunaga et al. 2002). One basic need is clarification of the differences in cloud microphysical characteristics, such as the drop size distribution (DSD), in convective...
متن کاملComparison of Three-Dimensional Double-Echo Steady-State Sequence with Routine Two-Dimensional Sequence in the Depiction of Knee Cartilage
Introduction: There are some routine two-dimensional sequences, including short tau inversion recovery (STIR), T2-weighted fast-spin echo (T2W-FSE), and proton-density fast spin-echo for diagnosing osteoarthritis and lesions of the knee cartilage. However, these sequences have some disadvantages, such as long scan time, inadequate spatial resolution, and suboptimal tis...
متن کاملRadar target echo cancellation using interrupted-sampling repeater
A method of using Interrupted-Sampling Repeater Jamming (ISRJ) to cancel radar target echo is proposed. After the principles of ISRJ are expounded, three conditions that should be met for radar echo cancellation are proposed, including range synchronization, phase coherent and amplitude match. Then, the restriction for key parameters of ISRJ, i.e. the repeater power, the delay time and frequenc...
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...
متن کاملThree Dimensional Radar Coincidence Imaging
Two dimensional (2D) radar coincidence imaging is an instantaneous imaging technique which can obtain 2D focused highresolution images using a single pulse without the limitation to the target relative motions. This paper extends the imaging method to three dimensions. Such a three-dimensional (3D) radar imaging technique does not rely on Doppler frequency for resolution and has an extremely sh...
