FIG. 5 is a method of generating marine / acoustic environmental data for generating a vertical sound velocity structure between a first point and a second point of the ocean, and firstly, observes the marine / acoustic environment of the ocean including the first point and the second point. (500) configures a constant grid DB of marine / acoustic environmental data for each grid (510).

6 is a diagram illustrating a specific execution process for the DB configuration (step 510) of FIG.

6 is an embodiment of a specific process of the DB configuration (step 510), which is currently detected by a sonar sonar fixed to the bottom of the ship in the navy to detect underwater obstacles floating on the sea floor or underwater This chapter describes the process of extracting marine and acoustic environmental data needed to analyze the detection environment.

In order to analyze sonar detection environment, vertical water temperature / salin distribution structure of marine / acoustic environment data is required. Data on vertical water temperature / salin distributions are used to calculate the vertical sound velocity of the ocean, which is important for simulating the propagation of sound waves used in sonar.

The formula of sound velocity structure is as follows.

C: Sound Velocity

D: Depth

S: Salinity

T: Temperature

Here, as shown in the horizontal water temperature distribution of Figure 6, through the above-described calculation process using the observation value corresponding to the region of interest may be composed of a constant distance DB of the marine / acoustic environment data.

However, since the constant grid DB may use a pre-built DB as shown in FIG. 1, steps 500 and 510 may not be included in a method for generating marine / acoustic environment data by design.

Next, the marine / acoustic environment data of the first point is extracted through the measurement at the first point (520).

FIG. 7 is a diagram illustrating a detailed process of extracting marine / acoustic environment data (step 520) of FIG. 5.

As shown in (a) shown in FIG. 7, if it is desired to create a vertical sound velocity structure between the first point A of the ocean and the second point B, first of all, the first point A of the ocean In other words, the above-mentioned 'ocean observation' is performed to obtain marine / acoustic environmental data required according to the purpose.

The marine / acoustic environment data of the first point as shown in (b) of FIG. 7 may include a vertical distribution of water temperature or salinity of the first point.

Next, the environmental variability between the first point and the second point is analyzed using the marine / acoustic environment data extracted from the marine / acoustic environment data regular grid DB configured by ocean / acoustic environment observation (530).

8A and 8B illustrate detailed processes of the analysis of environmental variability (step 530) of FIG.

Referring to FIG. 8A, the variability analysis step 530 may be performed by using a vertical distribution of water temperature or salinity extracted from a constant grid of marine / acoustic environmental data previously configured by ocean / acoustic environmental observation. In operation 801, a variable component causing variation in sound speed between two points is extracted.

Next, an eigen-value and an eigenvector for the extracted volatile components are calculated (802).

Using the calculated eigenvalues and eigenvectors, the marine / acoustic environment data between the first and second points is decomposed (803).

In order to create a vertical sound velocity structure between the first and second points of the ocean, it is necessary to take into account the characteristics of the ocean's water temperature / salin, etc., which affect the change in the speed of sound. It refers to information on the characteristic distribution such as vertical water temperature / salin between the corresponding points to consider the characteristics of the lamp.

The change in the vertical water temperature distribution between the first point A and the second point B of FIG. 7A may exist as shown in FIG. 8B, but simple interpolation is performed by the conventional method. When performed, it cannot express the variability of the ocean such as (b) of FIG. 8B.

Therefore, in order to consider the environmental variability of the ocean, it is necessary to perform the environmental variability analysis step 530 to extract the main components of the environmental variability of the ocean using the vertical distribution of the marine / acoustic environment data made of a certain grid .

Next, the high resolution marine / acoustic environment data between the first point and the second point is generated using the sea / acoustic environment data and environmental variability of the first point (540).

The marine / acoustic environment data shown in FIG. 9 is used by using the marine / acoustic environment data DB for analyzing the detection environment of the sonar constructed through the specific process of the DB configuration (step 510) of FIG. 6 described above. The resolution is generated by selecting a resolution from the first point A to the second point B according to the frequency of the sonar.

The high resolution marine / acoustic environment data may specifically include a change in vertical sound velocity relative to the point passing while moving from the first point to the second point.

In addition, by analyzing the spatial and temporal changes of the eigenvalues and the eigenvectors, it is possible to generate a vertical sound velocity change with respect to the point passing while moving from the first point to the second point.

10 is a flowchart illustrating a method for modeling underwater weapon system performance according to an exemplary embodiment of the present invention.

Here, steps 500 to 540 may be performed through the same process as the marine / acoustic environment data generation method of FIG. 5 described above. However, steps 500 and 510 may be pre-built as shown in FIG. 1. It may be possible to use an existing DB, so it may not be included in the marine / acoustic data generation method by design.

Under the assumption that a DB based on marine / acoustic environmental data generated through such a process is held, the model of the underwater weapon system modeling condition is input (1000), and the high-resolution marine / acoustic environmental data and input underwater weapons from the database are held. Underwater weapon system performance modeling is performed based on the system modeling condition (1010).

However, in some cases, the model may be performed based on a preset condition or a default value without receiving the input of the input step 1000.

Meanwhile, the above-described embodiments of the present invention can be realized in a general-purpose digital computer that can be created as a program that can be executed by a computer and operates the program using a computer-readable recording medium. The computer-readable recording medium may include a storage medium such as a magnetic storage medium (eg, a ROM, a floppy disk, a hard disk, etc.) and an optical reading medium (eg, a CD-ROM, a DVD, etc.).
