The Propagation of Pulse in Sea Water
نویسنده
چکیده
A propagation of pulse generated by an electric dipole is studied. A general formula for the electric field, which is uniformly valid for large distance and time, is presented. Fourier transform, stationary phase and simple contour integration methods are applied. 1. CURRENT PULSE AND FOURIER TRANSFORM Electric dipole is excited by a current I(t) = I0f(t) where f(t) is a pulse. The Fourier transform of this pulse is defined as

Acoustic propagation analysis in the front of saline water mass in the Gulf of Aden
Background and Objectives: Influence of water mass on sound propagation in the Gulf of Aden underwater acoustics used for communication, navigation and identification of objects by both humans and marine mammals and for investigating the detrimental effects of anthropogenic activities (e.g. pile driving, seismic survey and ships) on marine animals. The Gulf of Aden presents a unique ecosystem t...
متن کاملThe Effect of Water Surface and Sea Bottom on Sound Propagation in Persian Gulf
Whether exploratory or commercially, acoustic fishery benefits are important in finding a school of fish and other aquatics, but using this procedure and state accurate detailed information for the whole specifications of organisms require sufficient information of sound speed changes, course of ray propagation and their rate of absorption and attenuation . This research has considered the qua...
متن کاملPulse spreading and correlation loss in shallow water environments with rough sea surfaces and bottoms
Active sonar pulses suffer time-spreading, distortion, and de-correlation due to multipath propagation and reflections from rough boundaries. Correlation of the received distorted pulse with the transmitted pulse leads to degradation in pulse compression gain in comparison to the ideal case of a received pulse being simply a time-shifted, amplitude-scaled replica propagated along a single direc...

متن کاملEffects of water temperature and migration time on some fecundity indices and fertilization rate of female Kutum, Rutilus frisii kutum, migratory to Shiroud River in the southwest Caspian Sea
Kutum, Rutilus frisii kutum, is an commercially important fish in the Caspian Sea. The fish enters the rivers leading to the Caspian Sea for spawning. One of these rivers is Shiroud River. In the artificial propagation process of Kutum, different factors are involved in quality and quantity of female broods eggs and also in the best temperature and migration time for spawning. The influence of ...
متن کاملUnique Solution of Short Pulse Propagation in Nonlinear Fiber Bragg Grating
In this study, a new numerical method is introduced to obtain the exact shape of output pulse in the chalcogenide fiber Bragg grating (FBG). A Gaussian pulse shape with 173 ps width is used as an input pulse for lunching to a 6.6 mm nonlinear FBG. Because of bistable and hysteresis nature of nonlinear FBG the time sequence of each portion of pulse is affected the shape of output pulse. So we di...
