To solve the problem of low contrast and serious loss of detail information after dehazing directly using the atmospheric scattering model. This paper proposes a novel night image defogging model that combines the Retinex and the atmospheric scattering models. This model incorporates the best of both algorithms. Retinex can enhance the contrast of the image and the detailed information of the image. The atmospheric scattering model can clearly describe the imaging principle of the haze map, and restore the haze-free image from the root. In qualitative and quantitative experiments, this paper compares four methods on public datasets. This algorithm’s average image information entropy processed by this algorithm is 6.995, the average peak signal-to-noise ratio is 19.340, and the average structural similarity is 0.766. Compared with the other four algorithms, the comparative test results show that the algorithm in this paper can effectively remove the haze in the nighttime image, restore the detailed information of the image, and promote the progress of the algorithm.

Regarded as the most important object of marine environmental monitoring, wave condition especially the height, period measurement technology has comprehensively involved various means during the deepening of wave research. Among many wave measuring methods, wave measuring buoy is recognized as the most direct and accurate equipment. Acceleration integration and turbine flow meter constitute the traditional mainstream of wave testing. GPS and MEMS sensors have been developed to measure waves in recent years. Because buoy is a wave measuring equipment that directly contacts the sea surface, its measuring accuracy is higher than that of other wave measuring methods, so it is also considered by foreign countries as the most direct and accurate wave measuring equipment. In this paper, GPS and MEMS sensing technology are mainly used to analyze the wave height and period measurement. At the same time, the main development process of the wave height gauge is introduced extensively. Finally, the accuracy and repeatability of the wave height meter are tested by means of walking crane, certificated meter ruler and stopwatch. The test results show that it can meet the relevant standards of wave measurement and monitoring. On this basis, the sensor is tested in the South China Sea, and the reliability of the instrument is further verified. In one word, the paper can provide theoretical basis and technical support for the research and development of wave measurement equipment and promote the practical application in the field of wave condition monitoring.

During the installation of ultra-short baseline underwater acoustic positioning system, it is difficult to ensure that the array coordinate system and the surveying ship coordinate system completely coincide, and there is a certain systematic installation error, which affects the positioning accuracy of the system, so it needs to be accurately calibrated. According to the principle of coordinate transformation, this paper proposes a calibration method of installation error based on quaternion method, and constructs a three-dimensional coordinate transformation model. The simulation results show that the proposed method has obvious convergence of the underwater target distribution after calibration, and is superior to the classical Euler angle algorithm, which significantly improves the positioning accuracy of ultra-short baseline underwater acoustic positioning system.

In view of the uneven distribution of single beam measurement data density in the area with abrupt seabed terrain, it is difficult to form a refined digital water depth model to provide services for ship navigation, marine engineering construction, military activities and so on. In this paper, the area with large fluctuation of seabed topography is selected as a demonstration, and the three-dimensional interpolation methods such as linear interpolation triangulation method, nearest neighbor interpolation method and natural neighbor interpolation method are used to interpolate the single beam bathymetric data in the study area. Based on the two evaluation indexes of residual sum of squares (RSS) and root mean square errors (RMSE) and the cross validation evaluation method, the accuracy of the results of the three interpolation methods is evaluated. The final results show that when water depth interpolation is carried out in the area with large changes in seabed topography, the linear interpolation triangulation method has faster interpolation speed and the natural adjacent point interpolation method has higher interpolation accuracy. The research in this paper has practical reference value for the three-dimensional interpolation of single beam water depth data in the area with large seabed terrain changes.

In order to study the influence and characteristics of seamount on low frequency acoustic propagation in shallow sea, using the Finite Element Method (FEM) to set up a full-waveguide low-frequency acoustic propagation simulation model in shallow sea, and discussing the influence laws of different seamount on acoustic propagation. The simulation results show that the propagation law of sound energy flow is obviously different from before and after the seamount. with other conditions unchanged, with the decrease of slope angle, the loss of sound energy is less in front of the seamount, and the diffusion of sound energy is slower and tends to be gentle after crossing the summit. With the decrease of the height, the less sound energy is lost in front of the seamount. As the volume of the seamount shrinks, the hindrance effect of the seamount on sound energy propagation is weakened.

In the field of deep space exploration, remote sensors with cryogenic optics for reducing the optics radiation and increasing the remote sensing sensitivity are used for detecting celestial bodies at a long distance. A cryogenic infrared blackbody simulator working in the range of 40-300K which is continuously adjustable in front of the detector was developed, for the performance testing of the background limit detector data collection. The methods of performance parameters measurements for infrared detectors were analyzed in the paper, and the performance detection test of infrared detectors under room temperature and deep low-temperature were introduced. When in front of the cryogenic blackbody, the maximum value of integration time of the infrared detector could be 13 times longer than in front of room temperature blackbody. Meanwhile, the ratidetection rate was 15 times larger. The relationship between the working temperature of optical system and sensitivity of the system could be quantified. The result could be applied for the design of the remote sensing system.

One of the basic tasks of remote sensing image processing is change detection (CD). It aims to determine the change information in the region of interest and filter out the irrelevant change information. Existing methods are still inadequate in terms of depth feature extraction efficiency and lack robustness to pseudo change information. To overcome this problem, a multi-attention-based CD method is proposed in this paper. The proposed method optimizes and improves the existing feature extraction network, and introduces an attention mechanism in the feature extraction process, which can better extract the image feature information. A cascaded multi-attention module is designed, which can capture both remote dependencies and spatial dependencies to obtain a higher quality feature representation. The feature extraction and detection performance of the model is improved. In addition, a serious problem in CD is sample imbalance, and to overcome this problem, a batch-balance contrastive loss function is introduced, which uses batch weights to modify the class weights of the original contrast loss. Compared with other methods, the proposed method improves the F1 scores by 5.3% and 5.6% on the three publicly available benchmark datasets CDD and LEVIR-CD datasets, respectively. The experimental results show that the proposed method achieves state-of-the-art (SOTA) CD performance.
