Depth resolution data processing

Improved mathematical techniques for fusion and computer processing of the sensor data may, however, improve both the horizontal and the depth resolution attainable with these sensors if a rapid and convenient method of acquiring the sensor data can be developed. Ground-penetrating radar systems are limited in the depths to which they can "see " further, they tend to be somewhat delicate instruments that work best on smooth terrain, and they are not particularly well suited for use under rugged field conditions. Also, to date there is little evidence that airborne radars (or other sensors) can robustly detect buried ordnance under any but the most favorable conditions. 

Despite all the advances in instrumentation and methodology, the complete assignment and structural determination of large proteins are still time-consuming processes. There is a need for software to improve the resolution of NMR data and to accelerate the assignment and structural refinement processes. Driscoll et al.2,i reviewed this area of research in 1999, and the reader is referred to this article for an in-depth discussion of software advances prior to 1999. We will briefly mention some of these techniques, because they are still relevant, but will discuss in more detail advances since that time.
