The performance of torpedo homing system is affected by the high reverberation interference and multi-path effect in acoustic environment of the shallow water.

This paper highlights how to deal with the conflicts of bioenergy and food security,the realizing of potentials of marginal land through the breeding of appropriate "multi-use crops" which could be energy crops with other usefulness,as well as the effects of biomass industry to Chinese agricultural and rural development.

Based on numerical simulation method to analyze stress distribution of coal-pillar of both sides of filling roadway and to remove 'mutual influence of multi hole' caused by driving .

The summarization of GPS technologies in mitigating multipath effects;

Explicit expressions are obtained in this article for the causation of the multipath effect in the SW communication.

To solve the multipath effect, the NSS based on Geometrical Theory of Diffraction (GTD) for approach landing systems is presented, including the methods that have been applied, and the simulation results for hangars problem.

For inverse synthetic aperture radar (ISAR), the multipath effects introduce two artifacts in its reconstructed images, which greatly hinders radar target recognition and classification.

In this dissertation,the theory and realiztion of GPS based attitude determination technique are studied, multipath effects on GPS observables and carrier phase multipath mitigation are also analyzed.

A statistical model of the chaff cloud scattering and echo signal envelope was used to simulate the chaff clutter with multipath effects and the effective scattering coefficient of the chaff cloud as well as the multipath effects.
