している。 Generally, when installing a radio wave reflector as a target on the sea surface, the radio wave reflector is floated directly on the sea surface, or a means is provided in which the radio wave reflector is held by a support on a raft. The method of floating a radio wave reflector as a target directly on the sea surface is by using the "undulations" of the sea surface.
It also has the disadvantage that it is hidden between waves due to wind and waves, making it physically difficult to see from the apogee, and that the radar reflection cross section becomes extremely unstable. Also,
Fixedly installing a radio wave reflector as a target on a raft has the disadvantage that it cannot be quickly installed at a desired location.

It is equipped with an 8-sided corner reflector that functions as a reflector, and a compressed gas cylinder that stores a small density gas with a capacity sufficient to supply air to the balloon bag and inflate it to make it levitate. By attaching the radar, the radar will land on the water as a raft after functioning, and will be tied to the balloon bag with a connecting cable to stabilize the balloon bag in the air. The objective is to provide a floating radio wave reflector that is stable and can be quickly installed at a destination point.

られている。 As shown in FIGS. 1 and 2, in this embodiment, a floating radio wave reflector serving as a target is stored in a rocket-type target flying body 2, and a launcher 1 on a ship is used.
Explain the case of firing from. In Figure 2,
A compressed gas cylinder 3 forms the front part of the target vehicle 2 and is associated with a gas pressure regulator 4.
Inside the rear fuselage 8 are a balloon bag body 12, an eight-sided corner reflector 13, an air conduit 14, and a connecting cable 15 as shown in FIG.
and a swim bladder 7 are stored. The balloon bag body 12
is made of a soft material that allows radio waves to pass through easily.
The surface corner reflector 13 is foldable and made of a soft material. A timer switch 11 is used to set the operating timing of the fuselage separation device 5, and an external booster 9 is provided at the rear end of the rear fuselage 8.

By operating the connecting rope length adjuster 10 of the target flying object 2 stored together in a shape, the connecting rope 1 stored in a spiral shape inside the fuselage is adjusted.
5 to the balloon bag installation height A, pull out and cut off the remaining length to obtain a predetermined connection length.

Depending on the elapsed time since launch, the fuselage separation device 5 is activated, and the balloon bag 12 and corner reflector 1 are separated.
3. Separate the rear fuselage 8 of the flying body 2 in which the air conduit 14, connecting cable 15, and swim bladder 7 are stored using the fuselage separation device 5.

る。 The deceleration device 6, which is a part of the outer shell of the rear fuselage 8, deploys outward at the same time as the separation, the rear fuselage 8 rapidly decelerates, and the components stored inside the rear fuselage are smoothly pulled out of the rear fuselage. At the same time, the pull-out cable connecting the rear fuselage 8 and the top of the balloon bag body 12 is removed, and the compressed gas cylinder 3 is removed in conjunction with the pull-out cable.
is opened, and a gas having a lower density than air is rapidly blown into the balloon bag 12 through the air conduit 14. At the same time, air is also supplied to the floating bladder 7 attached to the compressed gas cylinder 3. Sufficient inflation of the balloon bag 12 by air supply causes the balloon bag 1 to become spherical as shown in FIG.
The targeting function is completed by deploying the 8-sided corner reflector 13 enclosed within 2, and the airborne radio wave reflector softly lands on the water surface while reducing its descent speed. As a result, the compressed gas cylinder 3 that continues to supply air to the floating bladder 7 that has landed on the water becomes a raft, and the altitude of the balloon bag 12 is fixed by the connecting cable 15 that connects the balloon bag 12 and this raft. Fixed at height.

能にする効果を得ることができるものである。 As is clear from the above description, in the present invention, the mechanical strength of the soft corner reflector 13 attached to the balloon bag 12 does not require a large strength because the balloon bag 12 also serves as a radome. By making it possible to use a large corner reflector 13 with a simple structure that can be fully expanded by the expansion tension caused by the expansion of the balloon bag 12, and by having a structure that floats in the air, it is more effective than conventional radio wave reflectors of this type. , it is possible to obtain a stable and large radar reflection cross section and the effect of enabling quick and reliable installation.
