DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an effectiveness calculating circuit,
In particular, the present invention relates to a firearm allocating device that effectively calculates a firing effectiveness in consideration of a main shooting direction and a main shooting range of a firearm, and preferentially allocates a firearm to a target within the shooting range.

[0002]

2. Description of the Related Art When attacking or intimidating an aircraft or a ship that has invaded airspace or territorial waters as a last resort, a commander specifies a target to be attacked against each of the firearms of a friend, This information is being communicated to the department in charge of firearms.

[0003] This procedure is called firearm allocation, and the procedure is as shown in FIG. 2, target information including the target position and its speed obtained by the radar / sensor system 203 and the like, the position and the position of the firearm system 204. Based on the firearm information including the range, the effectiveness calculation circuit 201 obtains the effectiveness (fire effectiveness of the firearm on the target) for each combination of the target and the firearm, and determines the result as the target / firearm combination determination circuit 20.
In step 2, the effectiveness is comprehensively determined (for example, a combination that maximizes the total effectiveness is made), the combination of the firearm and the target is determined, and the content is displayed and monitored by the display system 205. At the same time, it is transmitted to the firearm system 204.

A conventional effectiveness calculating circuit is a firearm allocating device for allocating a firearm, in a firearm allocating apparatus, a relationship between a target position / advancing direction / velocity and a firearm position based on the target information and the firearm information, and a firearm range. The validity is calculated based on the above. For example, the effectiveness M is represented by the following equation (1), where V _T is the target speed, R _{T is} the distance between the target and the weapon, and θ _T is the angle between the target traveling direction and the weapon as viewed from the target. See JP-A-63-38899).

M = M (V _T , R _T , θ _T ) (1)

[0006] Usually efficacy M is increased with respect to V _T, is a positive decreasing function with respect to R _T and theta _T.

As a conventional effectiveness calculation circuit, for example, Japanese Patent Application Laid-Open No. 63-38899 discloses an effectiveness calculation method based on the position of a firearm, the position and speed of a target without considering the range of the firearm and the range of fire. In order to solve the problem that firearms are assigned to targets that cannot fire and that effective effectiveness cannot be calculated even for targets that may fire, Determine the fireability of the firearm based on the fireable range of the firearm and the like in consideration of the speed of the flying pair fired from the firearm and the traveling speed of the target,
If there is no fire possibility, the effectiveness (M) is set to zero to prevent firearm allocation to non-fire targets,
If there is a possibility of shooting, the effectiveness is calculated based on the time until the target passes through the shooting range and the time until the target reaches the shooting range, and if the shooting time becomes longer, shooting is possible A configuration has been proposed to increase the number of opportunities. That is, the gazette discloses a configuration in which, when there is no possibility of fire, the possibility of firearms is prevented and the effectiveness is effectively calculated by the fire possibility determination means and the effectiveness calculation means.

In this case, there is a problem that the firearm requires an operation or time such as changing the direction of a sensor in order to capture the assigned target, and the firearm cannot be fired immediately.

Therefore, the present invention solves the above-mentioned problems, and effectively calculates the effectiveness of the fire in consideration of the main shooting direction and the main shooting range of the firearm, and preferentially assigns the firearm to a target within the shooting range. It is an object of the present invention to provide a validity calculation circuit that enables the above.

In the present invention, preferably, the effectiveness calculating means receives the target information signal and the firearms information signal, determines the possibility of shooting for each combination of the target and the firearm, and waits for an attack. Firing possibility determining means for calculating time and possible attack time, and calculating the effectiveness of each combination of the target and the firearm based on output information of the shooting possibility determining means, and outputting an effectiveness signal And a validity calculating means.

[0012] In the present invention, preferably, the inside and outside of the firing range judging means uses the information on the target T, the position of the firearm and the main shooting direction of the firearm, and the direction of the target and the firearm. Calculating an angle (θ _T ) between the main fire direction and comparing the angle with the main fire range (θ ₀ ) to determine whether the target is inside the main fire range of the firearm; It is characterized by.

In the present invention, preferably, the target information signal includes a position, a traveling direction, and a speed of the target.
