Abstract

<P>PROBLEM TO BE SOLVED: To solve problems in a method in which the transmission and reception of identification of friends or foes is performed by radio wherein, in the identification, a friend aircraft cannot transmit response by radio due to the reason of radio control, cannot accurately receive the response of a foe aircraft due to the communication interruption and the effect of an ionosphere, and radio interference occurs, and the size of additional devices must be cleared. <P>SOLUTION: When a flying vehicle 1 nears a tracking target, it transmits a transmission wave 15 with friend/foe identification code, and the friend aircraft 10 determines the presence or absence of the code by an identification code determination device 13. When the device determines that the code is present, the friend aircraft 10 emits flashing light 16. The flying vehicle 1 images the flashing light emission 16 of the lighting device of the friend aircraft 10 by an imaging device 7, and analyzes the imaged picture by a friend/foe identification device 9. When the flying vehicle is identified to be a friend by the friend/foe identification device 9, a flying stop instruction is given to a control part 6 to control the flying of the flying vehicle 1. <P>COPYRIGHT: (C)2004,JPO&NCIPI

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flying object system having an enemy / friend identification function in which a flying object system such as a missile has an enemy / friend identification function.
[0002]
[Prior art]
When shooting with a flying object, the shot object itself can identify the enemy or ally to prevent misfire of the friendly aircraft, and if it is identified as a friendly aircraft, the flying object can be invalidated It is important to have a function.
[0003]
As an example in which such a flying object itself performs enemy / friend identification, there is a conventional technique in which an enemy / friend identification device is provided on a flying object to perform enemy / friend identification by radio waves (for example, Patent Document 1).

[0005]
[Problems to be solved by the invention]
In the method of transmitting and receiving enemy / friend identification by radio waves, when identification is performed, the response of the allied device cannot be correctly transmitted due to radio control or other reasons, or communication interference, the influence of the ionosphere, etc. The problem is that there is a problem that the radio wave cannot be received, radio wave interference, and the size of the additional device.
[0006]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and has as its object to improve the identification probability when performing enemy or ally identification between a flying object and an ally.
[0007]
[Means for Solving the Problems]
The flying object system with an enemy / friend identification function according to the present invention includes an identification code adding device that encodes and adds a signal for enemy / friend identification to a transmission wave for target acquisition and tracking, An imaging device that captures a light-emitting image to be illuminated; and an enemy / friend identification device that analyzes the captured image to identify an enemy / friend. It includes a code determination device and a light emission control device that controls the light emitting device.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1 FIG.
Hereinafter, Embodiment 1 according to the present invention will be described with reference to the drawings.
FIG. 1 is a diagram assuming that a flying object has captured and tracked a friend in the flying object system with an enemy / friend identification function according to the first embodiment. Is shown. Various devices are provided in the flying object 1 and the friendly aircraft 10 shown in FIG.
[0009]
The enemy / friend identification performed between the flying object 1 and the ally machine 10 operates as follows.
When the flying object 1 approaches the tracked target, the identification code addition device 8 identifies a signal to the transmission wave for tracking the target generated by the transmission device 4 for the purpose of identifying the enemy or friend, and the action of identifying the signal to the enemy. The transmission wave 15 with the enemy / friend identification code is transmitted from the antenna 2 when the transmission timing is reached by the transmission / reception switching device 3 which switches the transmission / reception timing of the antenna 2 by encoding and adding it. The ally machine 10 receives the transmission wave 15 with the enemy / friend identification code by the antenna 11 and determines the presence / absence of the code by the identification code determination device 13. When it is determined that the code is present, the light emission control device 14 controls the light emission device 12 and causes the light emission device 12 to blink 16 and emit light. The light emission control device causes the blinking light emission 16 to blink in a specific pattern in order to improve the identification probability. The flying object 1 captures the blinking light emission 16 of the light emitting device 12 of the ally 10 by the imaging device 7 in front of the antenna 2, and analyzes the captured image by the enemy / friend identification device 9. If the enemy / friend identification device 9 identifies the friend, the enemy / friend identification device 9 issues a flight stop command to the control unit 6 that controls the flight of the flying object 1.
[0010]
According to this embodiment, it is not necessary to perform all of the enemy / friend identification by radio waves, so that the ally equipment cannot transmit a response due to radio wave control or the like, communication interference, influence of the ionosphere, etc. It is not possible to receive a response accurately, so that the probability of identifying an enemy or an ally can be improved, and an erroneous explosion of an ally can be prevented as much as possible.
[0011]
Note that the blinking light emission 16 of the light emitting device 12 of the ally device 10 may be any wavelength, such as infrared light, ultraviolet light, or visible light. The imaging device 7 of the flying object 1 may also select an imaging device in accordance with the wavelength of the blinking light emission 16 emitted from the light emitting device 12 of the ally device 10. A plurality of light emitting devices 12 of the teammate 10 may be provided in the teammate 10 so that the ten light emitting devices 12 can be imaged.
[0012]
Further, the type of the friendly aircraft 10 may be any type such as an aircraft, a ship, a tank, and the like, as long as it has a configuration including the antenna 11, the light emitting device 12, the identification code determining device 13, and the light emitting control device 14.
[0013]
Furthermore, when an existing radar warning device is provided in the friendly machine 10, the radar warning device may be provided with a light emitting device 12, an identification code determination device 13, and a light emission control device 14.
[0014]
Embodiment 2 FIG.
FIG. 2 shows a configuration of a flying object of the flying object system with an enemy / friend identification function according to the second embodiment. In the figure, 1 to 9, 15 and 16 are the same as the devices described in the first embodiment. In the second embodiment, the imaging device 7 provided in front of the antenna 2 is provided on the side of the body. It is provided on the front surface of the tunnel 17. In this case, the blinking light emission 16 from the opposite side provided with the tunnel 17 cannot be imaged by the flying object 1, but the flying object 1 causes the imaging device 7 to emit light from all directions. Fly while rolling the aircraft to be able to take images.
[0015]
According to this embodiment, since no obstacle is present in front of the antenna 2, the transmission wave 15 with the enemy / friend identification code is radiated into the air without attenuation or the like, so that the target tracking / capturing performance is deteriorated. Without this, the probability of identifying an enemy or an ally can be improved, and an erroneous explosion of an ally can be prevented as much as possible.
[0016]
【The invention's effect】
According to the present invention, when a friend cannot transmit a response due to radio wave control or the like, or communication disturbance, the response of the friend cannot be received accurately due to the influence of the ionosphere, etc., the identification probability of an enemy or friend is reduced. It is possible to prevent erroneous explosion of a friendly machine as much as possible.
