Description

  The present invention relates to a shooting control apparatus that controls shooting with a guided bullet against a target based on target information of a target that is flying.

  In a guided bullet system that deals with flying targets with guided bullets from the ground, the main configuration is equipped with a shooting control device that captures and follows the targets and controls the firing of guided bullets against these targets. Yes. In this type of shooting control device, a single shooting unit is configured as a guided bullet system in combination with a guided bullet for dealing with a target target, and further, this single shooting unit can be operated or a plurality of shooting units. And other systems, such as combining with other systems. The fire control device, which is the main configuration, is also configured in various device scales including a radar for capturing and following a target so as to meet the requirements in these operation modes.

  For example, when dealing with a flying target from the ground in one shooting unit, the shooting control device is configured with a radar scale that can reliably deal with a target in a desired region. The Then, the operation is made relatively mobile.

An example in which a plurality of shooting units are configured by network connection is also disclosed (see, for example, Patent Document 1). In the example disclosed in Patent Document 1, the flexibility is controlled by realizing a command function for controlling the whole by controlled linkage operation by each shooting unit without centrally managing a plurality of shooting units. It has an improved structure.

  By the way, in order to cope with a target that enters at high speed from a short distance, amongst the flying targets, it is required to detect the target as early as possible by the above-described shooting control device. . In other words, it is necessary to detect the target at a stage with sufficient time and distance so that various countermeasures can be taken against the target.

  However, many of the shooting control devices for dealing with flying targets from the ground are basically premised on the operation with mobility in one shooting unit. In such a conventional shooting control device, for example, in consideration of the radar coverage included in the configuration, there is a margin in terms of time and distance especially for a target that enters at high speed from a short distance. It may be difficult to detect in stages. For this reason, there is a possibility that a time margin for taking various countermeasures against the flying target cannot be obtained.

  The present invention has been made in consideration of the above-described circumstances, and it is possible to detect a flying target at an early stage and to provide various time-consuming measures for taking various measures against these targets even in the operation by one shooting unit. An object is to provide a shooting control device.

  In order to achieve the above object, a shooting control apparatus of the present invention is a shooting control apparatus that controls shooting by a guided bullet against a target based on target information of a target that is flying, and performs beam scanning in the radar coverage area. A radar unit that obtains target information of a target to fly; a target information receiving unit that receives target information of an adjacent area beyond the radar coverage; and the radar coverage based on the target information received by the target information receiving unit Using a flight path prediction unit that predicts a flight path of a target that enters the radar coverage from a distant adjacent area, target information acquired by the radar unit, and a prediction result from the flight path prediction unit, A beam control unit that controls beam scanning of the radar unit based on a result obtained by determining the presence of a target that needs to be dealt with, and based on target information acquired by the radar unit Run the interceptor operations on serial flying to the target, characterized by comprising a interceptor control unit for control the firing of the missile.

  According to the present invention, it is possible to obtain a shooting control apparatus having a time margin for detecting a flying target at an early stage and taking various countermeasures against these targets even in operation using one shooting unit. .

  Hereinafter, the best mode for carrying out the shooting control apparatus according to the present invention will be described with reference to FIGS. 1 to 3.

  FIG. 1 is a block diagram showing an embodiment of a shooting control apparatus according to the present invention. The shooting control apparatus 1 includes a radar unit 11, a target information receiving unit 12, a flight path prediction unit 13, a beam control unit 14, and a fire control unit 15.

  The radar unit 11 transmits a radar wave to a basic radar coverage area and receives and processes the reflected wave based on beam scanning control from a beam control unit 14 to be described later, and target information of a target flying in this area To get. Here, in the present embodiment, the target information to be acquired is target distance information, angle information, and speed information. The target information receiving unit 12 receives target information in an adjacent region beyond the radar coverage, which is the basis of the radar unit 11, for example, acquired by another system and sent to the shooting control device 1, and a flight path prediction unit 13 to send.

  The flight path prediction unit 13 receives the target information from the target information reception unit 12 and enters from the adjacent region beyond the radar coverage that is the basis of the radar unit 11 toward the radar coverage that is the basis of the radar unit 11. The target is detected and its flight path is predicted. The beam control unit 14 controls the beam scanning for searching the target over the entire coverage area of the radar unit 11. When the prediction result of the target flight path is received from the flight path prediction unit 13, the beam scanning for detecting the target toward the angularly limited area in the radar coverage including the predicted flight path is performed. Take control. Based on the target information acquired by the radar unit 11, the critical control unit 15 executes a critical calculation for the target, sends the calculation result to the subsequent stage, and controls the firing of a guided bullet (not shown).

  Next, the operation of the shooting control apparatus 1 according to the present invention configured as described above will be described with reference to the conceptual diagram of FIG. 1 and FIG. 2 and the flowchart of FIG.

  FIG. 2 is a model of the relationship between the radar coverage 1a of the shooting control apparatus 1 in this description, the basic radar coverage 1b that is a normal search area, the target information acquisition area 2a by the other system 2, and the target 3. FIG. In the following description, as an example, the target 3 that needs to be dealt with first jumps to the target information acquisition area 2a by the other system 2, and after the target information of the target 3 is acquired in this area 2a, the target 3 The operation when the shooting control apparatus 1 enters the radar coverage 1a is taken up.

  FIG. 3 is a flowchart for explaining the operation of the shooting control apparatus 1 according to the present invention in the above-described scene. First, the basic radar coverage 1b is searched, and target information in this area is acquired. That is, the beam control unit 14 performs beam scanning control for searching the entire radar covered area 1b to the radar unit 11, and the radar unit 11 sets the target region based on the beam scanning control. Radar waves are radiated toward it. The reflected wave is also received by the radar unit 11 and subjected to reception processing such as amplification, frequency conversion, and detection, and signal processing such as target detection, and then target information is acquired (ST201).

  At the same time, the target information acquired by the other system 2 is sent to the shooting control apparatus 1. This target information is for a target existing in the target information acquisition region 2a by another system, and is target information in an adjacent region beyond the basic radar coverage 1b. In the case of FIG. 2, target information of target 3 is sent. The target information of the target 3 that has been sent is received by the target information receiving unit 12, and then sent to the flight path prediction unit 13 (ST202).

  It is determined whether or not the target 3 is a target to be dealt with, and if it is determined that the target is to be dealt with, the target 3 from the other system 2 received via the target information receiving unit 12 can be detected early. Based on the target information, the flight route prediction unit 13 performs a prediction process to predict the flight route. In this prediction processing, prediction is performed by applying, for example, statistical prediction filter processing to the acquired target information of the target 3. This prediction result is sent to the beam controller 14 (ST203).

  The beam control unit 14 determines the presence of a target that needs to be dealt with based on the obtained target information and the prediction result (ST204). As a result, in this example, the target 3 is extracted as a target that enters the radar coverage 1a (Y in ST204).

  Next, the beam control unit 14 uses the angularly limited region 1c in the radar coverage 1a in which the entry of the target 3 that has not yet entered the radar coverage 1a is predicted to be a target region, as a target region. The beam scanning control is performed on (ST205). By limiting the angle and concentrating energy in the limited range, the target 3 is detected by the radar unit 11 at a farther distance, that is, at a farther distance than the radar coverage 1a. After detection, the radar unit 11 continuously acquires target information of the target 3 (ST206).

  The target information of the target 3 acquired in this way is sequentially sent to the fire control unit 15. The critical control unit 15 receives the target information and performs a critical calculation necessary for handling with the guided bullet, and sequentially updates the calculation result with the latest target information (ST207). The result of this critical calculation is sent from the critical control unit 15 to the subsequent device to deal with the target 3 such as the firing of a guided bullet (ST208). The result after the countermeasure is confirmed by, for example, target information continuously acquired from the radar unit 11 (ST209).

  As described above, in the shooting control apparatus according to the present embodiment, in addition to the acquisition of target information for a target entering the radar covered area 1b which is the basis of the shooting control apparatus 1, an adjacent area beyond this radar covered area 1b. Is received, and the flight path of the target predicted to enter the radar coverage 1a is predicted. Then, the radar beam scanning control is performed on the angularly limited region 1c including the predicted flight path, and the target is detected further than before the limitation. As a result, the target can be detected at an early stage in a stage where time and distance are sufficient.

  Also, when dealing with a flying target with a guided bullet, the meeting point between the target and the guided bullet can be set from a region farther than before. Therefore, it is possible to expand the area that can be dealt with even in the operation with one shooting unit, and for example, it is possible to deal with multiple times with guided bullets, select other countermeasures based on time margin, etc. Various countermeasures can be taken.

  In the flowchart of FIG. 3, as a method of performing beam scanning in step ST205, in addition to the case of searching for a beam scanning at a plurality of positions → following a beam scanning at one position, the search is skipped and directly followed. It is also possible to migrate to. In this case, since the operation time for the search time can be omitted, the time margin can be further increased.

The conceptual diagram which models and shows an example of the relationship between the shooting control apparatus of FIG. 1, and the target which flies. The flowchart for demonstrating operation | movement of the shooting control apparatus of FIG.
