Evaporation duct forms over the ocean surface and have a strong impact on near-surface radar propagation. The statistical features of spatio-temporal distribution of evaporation duct are of great importance to the design and application of ship borne electromagnetic systems. High spatial resolution (0.312°×0.313°) climate database of evaporation duct was established based on up to date National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) data and the NPS evaporation duct model. The spatial resolution was about 39 times higher than the existed climate database (1.875°×1.875°). The statistical features and the physical mechanism of spatio-temporal distribution of evaporation duct for the South China Sea were analyzed in detail based on the database. The distribution features of the evaporation duct height for different sea areas and months were obtained. The relative results can be applied to ship borne radar and communication systems design and planning of operation.

Studying low frequency sound transmission through water-air interface can help understand airplane-generated sound for acoustic remote sensing and effects of airborne sources on marine life. In this paper ray theory and wave theory are utilized to evaluate the acoustic transparency. Ray theory is first used to calculate the energy of the plane and spherical wave that transmits from water to air. Wave theory is then utilized to study spherical wave transmission through water-air interface. By comparing the results obtained from two theories, it is found that acoustic transparency can be derived using both ray and wave theory. Because acoustic transparency derived using ray theory is slightly smaller than that of the wave theory, it is thus called Enhanced Transparency as opposed to Anomalous Transparency proposed by Godin. By incorporating the inhomogeneous wave, wave theory does provide more significant transparency, especially in low frequencies. The results have been further extended to liquid-gas interface.

When signals exhibit non-Gaussian statistics, nonlinear signal processing techniques offer advantages over their linear counterparts. Nonlinearity in high-resolution synthetic aperture radar (SAR) imagery is an intrinsic phenomenon often overlooked in the radar literature. In this paper, we study the nonlinear dynamics, and the effect of detection, in SAR imagery. To this end, two complementary methods for exposing the nonlinear statistics are presented. The first method utilizes histogram fitting with relevant statistical models. The second method is based on hypothesis testing. Our results are demonstrated on real-world Radarsat-2 target chips. It is found that in the presence of extended targets (e.g., ships), the nonlinear effect in the SAR chip is predominant. Nonlinearity is observed to be negligible in the absence of extended targets. As the SAR chip is detected, the nonlinear dynamics are either diminished/altered (i.e., for power-detection) or obliterated (i.e., for magnitude-detection). To take full advantage of nonlinear statistics, it is recommended to utilize the complex-valued SAR image rather than the detected one. Furthermore, the Student's T location-scale distribution is seen to offer an excellent model for the SAR chip.

In this study, we have applied normal mode analysis on recent past storm events in the Gulf of Tonkin and the Leyte Gulf. The normal modes for each location are obtained from the previously developed unstructured normal mode decomposition solver based on the finite element method. The analysis of the two recent past storm events using the normal modes derived from the solver has been investigated in these two locations. The first event is tropical cyclone NARI (2013) in the Gulf of Tonkin, Vietnam and the second one is the super typhoon HAIYAN (2013) in the Leyte Gulf, the Philippines. Apart from obtaining the site-specific storm hazard summary through the normal mode shape, the study also aims to gain a deeper understanding on how normal modes contributed to the overall surge from the analysis of these past storm events.

Dynamic modeling and simulation of remotely-operated vehicle (ROV) are essential for search and rescue mission using AUV in remote distance. For initial model, hydrodynamic coefficients used in the ROV dynamic model are estimated using computation and analytical methods. The control strategy from launch to recovery is simulated using MATLABTM and SimulinkTM software. A three-dimension animation for ROV underwater operation is used to visualize the launch and recovery process of the AUV. The control simulation using a sliding mode controller (SMC) is designed to control the surge, sway, heave and yaw positions and velocities of the ROV under the sea wave and current disturbances. Simulated results show that the ROV is able to capture the AUV under the effect of current and wave disturbances.

With the depletion of land resources, marine resources development and utilization become increasingly apparent. Accompanied by the development of marine resources from nearshore extension to the deep ocean, Unmanned Underwater Vehicles (UUVs) become key instruments. Generally, UUVs include autonomous and tethered types; each has its advantages and disadvantages. Through the use of combined vehicle systems, we could take advantages of both systems. With the recent advent of seafloor observatories, deep submergence science is poised to enter a new research era where scientists will gain a more detailed understanding of various seafloor features. In this study, the Autonomous Underwater Vehicle (AUV) path planning in west Good Weather Ridge (119 55', 22 15') with the multi-beam echo sounder to obtain underwater topography. In order to observation the environment, the Remotely Operated Vehicle (ROV) is hired to carry out the terrain image at 1350m water depth in detailed. This experience will help to build future underwater investigation capabilities.

This paper presents the dynamic features of gravity waves based on coherent radar observations. We demonstrate that it is practical to detect wave breaking events via the sea surface backscattering intensity and Doppler velocity. Both parameters are acquired from coherent X-band radars operating at grazing incidence. Our measurements show a range dependency of the Doppler velocity which results from the wave shoaling as well as wave shadowing due to the low grazing angle of the observations. After separating these two effects, we can estimate the energy loss due to wave shoaling and wave breaking.

Pulse propagation in the surface duct with the source far below the duct is analyzed. Experimental results show that through the duct, the sound can propagate to the range much farther than that predicted by the ray theory. Besides, the propagation range is strongly related with the signal frequency. This propagation path is reproduced using the normal mode model. Furthermore, the ray representation of the normal mode is used to illustrate the mechanism of this surface-duct-related arrival. It is found that the arrival is due to the diffraction when a ray grazes the bottom of the surface duct. For lower frequency, the grazing angle is larger. Therefore, the energy diffracted back to the surface duct is weaker.
