Aggregation refers to an action of aggregating troops scattered in different areas to a designated area, and sometimes is also called aggregation in a state of temporary stay or gathering standby after completion of combat or other tasks. Any form of staging is typically performed by moving from the original configuration location, collapsing the formation, reaching a certain geographic location, etc. The main purpose of the gathering is to gather scattered troops, deploy combat tasks or perform other tasks, rapidly complete combat readiness, or put troops in a more favorable combat situation, etc.

In modern combat, the scout monitoring capability, the three-dimensional maneuvering capability, the remote accurate striking capability and the like are unprecedented, so that the threat suffered by the army in the gathering process is greatly enhanced. The gathering under modern conditions is to select a plurality of gathering areas according to conditions such as enemy, topography, tasks, soldier formation and the like, so that the range of the gathering areas is enlarged, and the allocation area of armies is enlarged. In the process of temporary stay, movement or furling of the army, the army needs to be strictly organized and implemented according to the upper level intention and the on-the-surface condition, and is carried out in time, hidden and evacuated; the effective protection of the surrounding organization against air, ground and information attacks strengthens the security measures such as reconnaissance information, warning, camouflage, deception, engineering, guard, adjustment service and the like and the protection against nuclear chemical weapons attack and the like so as to quickly and safely enter a preset region. In order to reduce the probability of being hit by enemy fire during assembly, the residence time in the assembly region is shortened as much as possible, and the motor and combat preparation is made at any time.
When the offshore voltaic is executed, if more than one gathering position suitable for the opponent ship object in the current battle sea area can be determined in advance according to the characteristics of the opponent ship object, the data volume and time delay of the onsite informatization processing of the offshore voltaic can be shortened, and the technical and thermal disadvantages of the battle ship are eliminated.

The information processing can be applied to various subdivision areas including offshore voltaics.
Marine vowels in general refer to measuring distance with radar, then covering the shot by means of fire advantage after the ship has entered range, and then determining whether it is necessary to withstand the near shot based on the vowels. However, in the case where the radar and the fire of the naval vessel are in relative advantages, the on-site monitoring of the enemy naval vessel can be realized by virtue of the technical and fire advantages, and the first-step striking is performed after the target is monitored. If the radar and the firepower of the naval vessel are in relative disadvantages, the sea area environment of the sea voyage needs to be treated in advance, the sea gathering position of the target naval vessel suitable for voyage is extracted and predicted, so that the data volume of the naval vessel field treatment is reduced, the reliability and the instantaneity of the judgment result are improved, the technical and firepower disadvantages are shortened and even eliminated, however, the current lack of reliable data and an effective advanced judgment mechanism help the naval vessel reduce the field treatment data volume, and the firepower control speed of the naval vessel cannot be improved.
In order to overcome the defects, the application discloses an offshore voltaic prediction system and method, which are used for removing a plurality of offshore areas which do not belong to suspected aggregation areas in all offshore areas by utilizing the safe running depth of a opponent ship object and the mapping relation between sea surface color change trend and sea water depth under high visibility, so that analysis time is shortened for analyzing the corresponding sea voltaic areas based on the aggregation areas, and the success rate of blocking the opponent ship object is improved.
As shown in fig. 1, a technical flow diagram of an offshore voltaic forecast system and method according to the present application is presented.
Firstly, respectively analyzing and monitoring the safe running depth of a ship object and the mapping relation between sea surface color change trend and sea water depth under high visibility by utilizing the characteristics of the ship object and the color distribution characteristics of the offshore water surface, so as to provide two different customization preparation data for the subsequent screening of suspected aggregation areas;
as shown in fig. 1, an encryption database is adopted to store the mapping relation between sea surface color change trend and sea water depth under high visibility, namely the mapping relation of sea surface color depth;
specifically, the analysis process of the two different customization preparation data is as follows:
the safe running depth of the monitoring ship object is a multiple of the draft of the monitoring ship object;
the composition color of visible light can be obtained through the prism, and the blue light with the wavelength of about 4500-5200 angstroms is generally defined; green light with a wavelength of about 5200-5600 angstroms; light with a wavelength of about 6250-7000 angstroms is red light, wherein 1 angstroms = 0.1 nanometers; any light can be decomposed into three colors of red, green and blue, except for red, green and blue monochromatic light or light mixed by only two kinds of monochromatic light of red, green and blue. Among the three kinds of colored lights, the order of the wavelength from long to short is red, green and blue, and the longer the wavelength is, the faster the absorption speed of the light is, therefore, in the change of the water depth of the position of the sea surface from shallow to deep, the red light has the fastest absorption speed, so that the red channel value of the pixel point at the corresponding position in the remote sensing picture of the sea surface has the fastest descending trend, the blue light has the slowest absorption speed, so that the light reflected by the sea surface becomes more and more blue along with the increase of the sea depth, because the descending amplitude of other colors is faster than the descending amplitude of blue light, namely, in the deep sea area, the blue represented by the water depth is more accurately described as the faint blue after blue ink is added into the water, and the one-to-one mapping relation between the color channel value of the pixel point in the sea surface imaging area and the water depth of the entity position corresponding to the pixel point can be established based on the change rule;
secondly, completing signal conversion from a remote sensing satellite picture of each offshore aggregation area to be analyzed to a sea surface area depth map based on a mapping relation between sea surface color change trend and sea water depth under high visibility;
thirdly, comparing the depth value of the sea surface region depth map corresponding to each to-be-analyzed aggregation region with the depth value of the safety running depth of the monitoring ship object, so as to confirm whether the to-be-analyzed aggregation region is a screened suspected aggregation region or not, wherein the suspected aggregation region is used for the position prediction of a subsequent offshore voltaic region;
after the position of the suspected integration area is obtained, as shown in fig. 1, various position prediction modes may be used to perform position prediction of the offshore voltaic area associated with the suspected integration area, where point B is the center point of the suspected integration area, and point a is the center point of the offshore voltaic area associated with the suspected integration area.
The application has the key points that the characteristics of the monitoring ship object and the color distribution characteristics of the offshore water surface are fully utilized, two different customization preparation data are provided for the subsequent screening of suspected aggregation areas, and whether each aggregation area to be analyzed in the offshore is the suspected aggregation area or not is judged based on the two different customization preparation data, so that the operation amount of the on-site aggregation area identification is greatly reduced, and the reaction time of the offshore voltaic of the warship is shortened.
