Abstract

The present invention relates to a target management method for a naval ship combat system. The target management method for a naval ship combat system is employed for storing or managing information of a moving target object by using ship sensors. The target management method includes the steps of: using the ship sensors to detect the location of a ship to calculate coordinates of the ship at a ship reference point; using the ship sensor to detect a target location and calculating coordinate information of the target at a target sensing point; and applying a location correction function, which is for correcting location errors in coordinate information of the target, to correct location error values at the ship reference point and the target sensing point to calculate the target coordinate information at the ship reference point. The target management method corrects the errors occurring between the target location detected at the target detection point of the ship sensor and the target location detected at the ship reference point by using the location correction function, thereby calculating the target location and distance thereto more accurately.

Description

[0001] The present invention relates to a method for managing a naval vessel combat system,

The present invention relates to a method of managing a target of a battle battle system, and more particularly, to a battle battle that uses a DBMS (Data Base Management System) to identify and analyze major targets, And the target management method of the system.

Inside the trap operated by the Navy, there is a naval combat system in charge of command control and armed control functions. These traps combat systems include sensor systems that perform target identification, management and maneuver analysis of detected targets, combat systems to establish tactical situation, threat assessment and analysis, armed allocation and engagement planning, and monitoring / And a weapon system that performs engagement control.

Trap combat systems are equipped with a number of radar and autonomous sensors in the traps to monitor and detect target objects and to manage joint targets to manage them.

Target management in trapping combat system is a technology to store and manage the information of target object moving according to time. It is used to manage target information detected by user sensors, source Target fusion, management of system targets to manage fusion targets, system targeting to fuse system targets, and tactical target management to tactically manage fusion targets.

Here, the primitive target is the target generated by the input of the user's sensor and operator, the system target is the target generated after the primitive target detected by the user's sensor has undergone the fusion or disassembly process, and the network target is the common And the tactical target is a target that is generated after a comparison match or disassembly process between the target and the data link receiving target.

In this case, the joint target management in the trap combat system is largely classified into a target processing function for managing the tactical target through functions such as target fusion, comparison value, and calculation using the target information received from the mounted sensor and the data link, A target management function for expressing a target received from a sensor and a data link as a single target, a target editing function for creating, updating, and deleting a target using target information input from an embedded sensor and an operator input and a data link .

Conventional joint target management has a problem in that a large number of application programs must be executed in order to perform target management and identification, tactical situation editing, threat analysis, and armed allocation.

On the other hand, for target management tasks such as target fusion, fusion disassembly, comparison agreement, disassociation, threat evaluation list generation, etc., distance of target and azimuth, distance between target and target should be measured based on ownership.

That is, the data received from the radar shows information such as the target position, speed and direction at the time when the radar detects the target, and there is a difference between the time when the radar target is detected and the time when the target is measured have.

However, in the conventional position calculating method of a target, when data is received from the radar, the target position is calculated by recognizing it as being received at the reference time of the self-calibration, thereby causing a position error of the target.

The distance calculation function calculates and returns the distance between two objects represented by the radial coordinate system. The distance is calculated by using Equation (2) or Equation (3) instead of the straight distance, considering the earth spherical curvature.

Respectively.

You can use the spherical cosine law to find the distance between two objects on the earth. In the cosine law of spheres, distances are defined as angles. The cosine law in the sphere is as shown in Equation 3 and is useful for finding the curvilinear distances of two regions apart from each other on the earth. Let a, b, and c be sides of vertex A, B, and C of triangle ABC, respectively, and a = bcosC + ccosB holds and b and c are the same.
