It is concluded that the atmospheric duct effects result mainly in height error for radars.

Based on the fiber optical grating sensing principle and the sensing model of axial stress function on fiber optical grating,two factors which caused the Fiber Bragg Grating axial sensitivity shift are analyzed-elastic foundation effect and wave-guide effect caused by the fiber diameter change,and the changing curves were drew.

The influence of the atmospheric duct on the detecting range of shipborne radars;

Research on multi-path channel parameters in the marine atmospheric duct;

Study of the shadow zone of the radar in the atmospheric duct;

This paper introduces the form reasoos of atmospheric waveguide,sort and conditions of forming waveguide,analyzes the influences of atmospheric waveguide on the operating performance of shipborne radar,electronic countermeasure system and communication countermeasure system,finally presents the measure to.

Two factors, atmospheric waveguide and atmospheric noise, which have influence to the communication performance are pointed out in this paper.

Optical Radiometry and Radiant Calibration of Atmospheric Effect;

Atmospheric effect is one of the important factors affecting the results of mineral identification and mineral mapping in the application of imaging spectra.
