The performance of infrared (IR) surveillance systems is proportional to the ability of distinguishing the radiance of target from the background. In determining sea radiance as the background, experimental studies are incomplete and very expensive. The few simulation software packages that are available are limited to certain parameters and do not include all aspects of sea radiance. In this paper,...
The success of infrared surveillance systems is proportional to distinguishing the radiance of the target and the background. In this study, a simulation program, namely, DAMA (InfrareD SeA Modeling and Analysis) software is developed to calculate the total radiance and its components seen by an observer looking towards the sea surface. Total radiance is composed of thermal sea radiance, reflected...
Total Electron Content (TEC) is a key variable to measure the ionospheric characteristics and disturbances. The Global Positioning System (GPS) can be used for TEC estimation making use of the recorded signals at the GPS receiver. Reg-Est method that is developed by F. Ankan, C.B. Erol and O. Arikan can be used to estimate high resolution, robust TEC values combining GPS measurements of 30 s resolution...
The sea surface statistical models are directly related with the calculation of the total radiance reflected from the sea surface seen by the observer. Three major work which model the sea surface slope statistics are Cox and Munk, Mermelstein and Shaw-Churnside models. The reflected sea radiance observed by an observer is composed of path radiance, reflected sky radiance, reflected sun radiance and...
