TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tracking obstruction apparatus and a tracking obstruction method, and in particular, to a tracking obstruction apparatus and a tracking method suitable for deceiving a tracking type flying object that tracks a target detected by a radar and preventing tracking by the flying object. Regarding the method of obstruction.
[0002]
[Prior art]
Figure 21 FIG. 1 shows a diagram for explaining a conventional tracking disturbance method. Figure 21 In the figure, 10 is an aircraft (aircraft), 12 is a chaff cloud (a radio wave reflection cloud), 14 is a tracking type flying object guided to a radio wave radiation source, and 16 is a radio wave radiated from the aircraft 10 to the chaff cloud 12. It is an irradiation pattern.
[0003]
Next, a tracking disturbance method having the above configuration will be described.
The aircraft 10 scatters the chaff to form the chuff cloud 12, and then emits a narrow beam and sharply directional radio waves toward the chuff cloud 12. The radiated radio wave is reflected by the chaff cloud 12, and a part thereof is detected by the tracking type flying object 14. When a radio wave is reflected from the chaff cloud 14 toward the tracking type flying object 14, the tracking type flying object 14 determines that the chaff cloud 12 is a radio wave radiation source and is guided to the chaff cloud 12. As a result, the tracking of the aircraft 10 by the tracking type flying object 14 can be effectively prevented.
[0004]
[Problems to be solved by the invention]
By the way, in the conventional tracking obstruction method, the aircraft 10 emits a radio wave without accurately grasping the position of the chaff cloud 12. For this reason, in the conventional tracking disturbing method, there is a problem that a narrow beam and a sharply directional radio wave are not always directed to the chaff cloud 12, that is, a problem that the radio wave is not re-emitted (reflected) by the chaff cloud 12. .
[0005]
In addition, the conventional tracking obstruction method is a method that assumes a flying object (hereinafter, referred to as a “radio wave tracking type flying object”) guided by a radio wave radiation source as a tracking target. As a flying object that tracks a target, in addition to a radio tracking type flying object, for example, a flying object (e.g., a radar homing missile) that includes a radar that emits a detection wave and detects a target based on its reflected wave, such as a radar homing missile ( Hereinafter, a "radar homing type flying object" is known. Tracking by a radar homing type flying object cannot be hindered by merely reflecting radio waves on the chaff cloud 12. Therefore, tracking by a radar homing type flying object cannot be hindered by the conventional tracking hindrance method. As described above, the conventional tracking hindrance method still has room for improvement in hindering the tracking of various tracking-type flying objects.
[0006]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Elements common to the drawings are denoted by the same reference numerals, and redundant description will be omitted.
[0028]
Embodiment 1 FIG.
FIG. 1 is a diagram for explaining a tracking disturbance method according to the first embodiment of the present invention. In FIG. 1, reference numeral 10 denotes an aircraft, 12 denotes a chaff cloud, and 14 denotes a radio tracking type flying object guided to a radio wave radiation source. Also, in FIG. 1, reference numerals 18 and 20 indicate a detection wave and an interference wave emitted from the aircraft 10 toward the chaff cloud 12, respectively.
[0029]
FIG. 2 is a block diagram illustrating a tracking disturbance device mounted on the aircraft 10. As shown in FIG. 2, the tracking obstruction device includes a chaff dispersing device 22. The chaff spraying device 22 is a device for spraying the chaff from the aircraft 10 in a predetermined direction. The chaff spraying device 22 is installed above the support stand 24. The support 24 can arbitrarily change the direction of the chaff spraying device 22 within a predetermined range.
[0030]
The tracking obstruction device includes an antenna 26. The antenna 26 is installed on a support base 28 so that its directivity can be arbitrarily changed. A transmitter 30 and a receiver 32 are connected to the antenna 26. The transmitter 30 has a function of outputting a predetermined detection wave at a first intensity from the antenna 26 and a function of outputting a predetermined interference wave at a second intensity that is stronger than the first intensity. ing.
[0031]
The intensity of the radio wave output from the antenna 26 can be changed by, for example, changing the output of a signal supplied to the antenna 26 or changing the beam diameter of the radio wave output from the antenna. The transmitter 30 gives a large intensity to the interference wave by narrowing the beam diameter of the interference wave to be smaller than the beam diameter of the detection wave. The method of increasing the intensity of the interference wave is not limited to this, and a process of changing the output of the signal supplied to the antenna may be used together.
[0032]
The electric wave received by the antenna 26 is converted into an electric signal by the receiver 32. A position detection device 34 is connected to the receiver 32. When the reflected wave of the above-described detection wave is received by the antenna 26, the position detection device 34 detects the position of the object reflecting the detection wave. A control device 36 is connected to the position detection device 34. In the present embodiment, the operation of the tracking obstruction device is controlled by the control device 3.
[0033]
Next, the operation of the above-described tracking obstruction device and the contents of processing executed in the tracking obstruction method of the present embodiment will be described.
When the tracking obstruction device is activated, first, the chaff is sprayed in a desired direction from the chaff spraying device 22 mounted on the aircraft 10. As a result, a chaff cloud 12 is formed as shown in FIG. Next, the aircraft 10 radiates a narrow-beam, sharply directional detection wave 18 from the antenna 26 toward the chaff cloud 12. After the detection wave 18 is reflected by the chaff cloud 12, a part thereof is received by the antenna 26 of the aircraft 10. When the reflected wave of the detection wave 18 is received by the antenna 26, the accurate position of the chaff cloud 34 is detected by the position detection device 34.
[0034]
The aircraft 10 radiates the interfering wave 20 from the antenna 26 toward the chaff cloud 12 when the relative position between the aircraft 10 and the chaff cloud 12 becomes clear. At this time, the transmitter 30 further increases the interference power of the interference wave 20 by making the beam diameter of the interference wave 20 smaller than the beam diameter of the detection wave 18. The high-power interference wave 20 emitted from the aircraft 10 is accurately applied to the chaff cloud 12 and re-emitted by the chuff cloud 12. As a result, a high-power interfering wave reaches the radio tracking type flying object 14.
[0035]
As described above, according to the tracking disturbance method of the present embodiment, it is possible to irradiate the chaff cloud 12 with the high-power disturbance wave 20 after clarifying the relative position between the aircraft 10 and the chaff cloud 12. Therefore, a high-power interfering wave can reliably reach the radio tracking type flying object 20. Therefore, according to the tracking obstruction method of the present embodiment, tracking by the radio tracking type flying object 14 can be prevented with high accuracy.
