Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flying body defense method capable of effectively defeating a flying body guided toward a radio wave radiation source to effectively prevent an attack by the flying body.

2. Description of the Related Art FIG. 7 is an explanatory diagram of a conventional flying body defense method. In the figure, 1 is an aircraft, 2 is a chaff cloud emitted from the aircraft 1, 9 is a flying object such as a missile equipped with a radar sensor, and is guided by the radar sensor to destroy the target object. In this flight defense method, the aircraft 1
On the other hand, when the flying body 9 is launched, the aircraft 1 scatters radar reflection objects, which are small needle-like small pieces of aluminum foil or glass fiber, on which aluminum is vapor-deposited into the atmosphere, to generate chaff clouds. Then, a large reflected echo appears with respect to the radio wave transmitted by the opponent radar, and the echo reflected by the own aircraft is made inconspicuous to disturb the flying object.

In this case, the chaff cloud 2 is generated by pushing out a piston with explosives to emit a radar reflector packed in a cylindrical bullet into the atmosphere. The radar reflector scattered in the atmosphere floats in the air while rapidly diffusing, and after being sufficiently diffused, finally falls freely and falls to the ground or the sea.

When the chaff cloud receives a radar wave, a large number of needle-like small pieces individually serve as dipole antennas and reflect the radar wave. Therefore, the radar receiving side receives a large amount of radar echo, and thus the chaff cloud. The object behind the cloud echo will be obscured. Further, the radar receiver is saturated with a large amount of echo signals to deceive echoes from, for example, the own aircraft near the chaff cloud.

On the other hand, there is also a guidance type flying body which detects a radio wave radiation source and heads for the radio wave source. To such a guidance type flying body, a radio wave is emitted by itself to serve as a decoy. It is possible to deal with this by a disposable type jamming device.

[0006]

Since the conventional flying body defense method is configured as described above, it is possible to detect a radio wave radiation source and use it for a flight body guided in the direction of the detected radio wave source. On the other hand, there was a problem that the method of protecting the flying body by the chaff cloud was not effective.

Further, the disposable type jamming device which emits radio waves by itself and becomes a decoy has a problem in that the cost is increased and the device itself is enlarged, which is not suitable for an aircraft.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to obtain a low-cost and effective flying body defense method against a flying body which is guided by a radio wave radiation source. To aim.

Embodiment 1 FIG.

Next, the operation will be described. A chaff cloud is already formed by the chaff that has been scattered, and the aircraft 1 irradiates the chaff cloud with a narrow-beam sharp electric wave. The chaff cloud reflects the radiated radio waves, part of which is detected by the radio wave source induction sensor of the flying body 3, and the flying body 3 is determined to be the radio wave radiation source.
Guided to. In this case, the aircraft 1 radiates radio waves from outside the detection coverage area of the flying body 3 toward the chaff cloud 2, thereby ensuring the safety against the attack of the flying body 3 of the aircraft 1 and The survival rate is higher than that of radio wave irradiation from within the detection coverage area.

Example 2. FIG. 2 is an explanatory diagram showing the configuration of a flying body defense method according to a second embodiment of the present invention. 2, the same or corresponding parts as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. In the figure, 1a is the first
Aircraft (aircraft), 1b is a second aircraft (aircraft),
Reference numeral 4a represents a radio wave irradiation pattern when the first aircraft 1a irradiates the chaff cloud 2 with a radio wave, and 4b represents a radio wave irradiation pattern when the second aircraft 1b irradiates the chaff cloud 2 with a radio wave.

In the flying body defense method of this embodiment, the first aircraft 1a and the second aircraft 1b irradiate the chaff cloud 2 with radio waves from different directions. Chaff clouds 2 from the first aircraft 1a and the second aircraft 1b
The radio waves are radiated alternately or simultaneously.
Therefore, the strength of the reflected radio waves in the chaff cloud 2 when the radio waves are emitted alternately or simultaneously from the first and second aircrafts 1a and 1b, respectively, is as follows. Due to the difference in the positional relationship and the distance between them and the strength of the radio wave radiated from the radio wave radiation source that is erroneously determined by the flying body 3, as a result, the radio wave radiating source that is erroneously determined may be separated from the flying body 3. By judging that the aircraft 3 is approaching, the deception effect on the flying body 3 is increased, and the survival rate of the aircraft 1a, 1b against the attack of the flying body 3 is improved.

In addition, the first aircraft 1a and the second aircraft 1b have the chaff clouds 2 from outside the detection area of the flying object.
By irradiating radio waves to the aircraft, the safety of the first aircraft 1a and the second aircraft 1b against the attack of the flying body 3 is secured, and the survival rate is higher than that of the radiation from the detection coverage area of the flying body. Will be larger.

Example 3. FIG. 3 is an explanatory diagram showing the structure of a flying body defense method according to a third embodiment of the present invention. 3, parts that are the same as or correspond to those in FIG. 1 are assigned the same reference numerals and explanations thereof are omitted. In the figure, 2a, 2
Reference numerals b and 2c denote a plurality of chaff clouds (radio wave reflecting means).

The aircraft 1 sequentially switches the targets to be radiated with radio waves in the order of, for example, chaff cloud 2a, chaff cloud 2b, and chaff cloud 2c. As a result, the radio wave source induction sensor of the flying object 3 is initially set in the chaff cloud 2a as the direction of the radio wave radiation source.
Direction, then chaff cloud 2b, then chaff cloud 2c
Is detected and the flying body 3 is finally guided toward the chaff cloud 2c other than the aircraft 1, and the safety of the aircraft 1 against the attack of the flying body 3 is secured.

Further, the irradiation of radio waves to the chaff cloud 2a by the first aircraft 1a and the irradiation of radio waves to the chaff cloud 2b by the second aircraft 1b are performed alternately. The chaff clouds 2a and 2b are formed at a certain distance with chaff scattered intermittently.

Therefore, the flying body 3 judges that the chaff cloud 2a is the radio wave radiation source when the first aircraft 1a is radiating radio waves to the chaff cloud 2a, and the second aircraft 1b is the chaff cloud. When irradiating the radio wave to 2b, the chaff cloud 2b is determined to be the radio wave radiation source. Therefore, the flying body 3 alternately determines the chaff cloud 2a and the chaff cloud 2b as the radio wave radiation sources, and the guidance system of the flying body 3 is disturbed, and during this period, the first aircraft 1a and the second aircraft 1a are disturbed. The aircraft 1b can escape to a safe area where the flying body 3 does not attack.

Further, since radio waves are radiated from different flying bodies to each of the chaff clouds 2a and 2b, the relationship between the distance and the angle between the chaff clouds and the flying body radiating the radio waves for each chaff cloud. Moreover, the distance and angle relationship including the flying object 3 are different, and the intensity of the radio waves reflected by each chaff cloud will fluctuate greatly. The deception effect for capturing radio wave sources is increased.

Example 5. It should be noted that the radio wave radiating means for radiating radio waves to the chaff cloud is not easily lightened and miniaturized at present, but it is a discard type, that is, a discard type radio wave jamming device which is a radio wave radiating means of a disposable type and its aerial. When the launch device can be installed on a ship, etc., or if it can be installed on an aircraft, when this dumping type electromagnetic interference device is projected from the ship to the sky or emitted from the aircraft to the air and the chaff cloud is irradiated with radio waves. It is possible to cause the flying body to detect the reflected radio waves of, and misguide the flying body guided toward the own ship or the own aircraft toward the chaff cloud. The discard-type radio wave jamming device that irradiates the chaff cloud 2 with radio waves is disposable, and thus is disadvantageous in cost, but the cost disadvantage can be eliminated if the chaff cloud 2 is collected and reused. Further, since the radio waves are not radiated to the chaff cloud 2 from the ship or the aircraft, the deception effect of the radio wave radiation source is insufficient, and even if the flying body targets the radio wave irradiation means, the ship Alternatively, the safety of the aircraft can be secured.

FIG. 5 is an explanatory view showing a flying body protection method according to a fifth embodiment of the present invention. Reference numeral 5 is a discard type radio wave jamming device (radio wave irradiating means), and 6 is a dump type radio wave jammer emitted into the air. It is a parachute for increasing the flight time of the device 5.

Embodiment 6 FIG. In addition, the radio wave interference device provided on the ship is used to detect the reflected radio waves when radiating radio waves to chaff clouds to the flying body, and the flying body guided to the own ship and the aircraft of the ally is chaffed. It is possible to erroneously guide the user toward the cloud. In this case, it is not necessary to equip the emission device of the radio wave irradiation means as in the fifth embodiment.
Also, in the case of the ship-equipped radio interference device, unlike the case where it is mounted on an aircraft, the weight and volume are not so limited, so it is possible to make the ship-equipped radio interference device highly functional,
It is possible to flexibly adjust the intensity and directivity of the irradiation radio wave while judging the deception effect of the radio wave radiation source on the flying object, and to maximize the deception effect of the radio wave radiation source on the flying object. .
