In the figure, 1 is a receiving antenna, 2 is an amplifier, and 3 is a transmitting antenna.The receiving antenna 1 is connected to the input terminal of the amplifier 2, and the transmitting antenna 3 is connected to the output terminal.
Note that the arrows indicate the flow of signals. Further, the receiving antenna 1 and the transmitting antenna 3 are arranged so as to face in the same direction. Although not shown,
Needless to say, a power source for operating the circuit portion is provided within the flying object.

して充分なものを構成することができる。 Therefore, when a flying object with the above configuration is flown at high speed and searched for by radar etc. or captured by another flying object having a radio proximity fuse, the receiving antenna 1 provided on the flying object The radio waves input to the antenna are amplified to a predetermined level by the amplifier 2, and then transmitted from the transmitting antenna 3 in the direction in which the radio waves arrive (radar side), and from the radar side, it is apparently recognized as an object larger than a flying object. It is. In other words, projectiles such as artillery shells and rockets have a very small radar reflection cross section due to their shape and size, so they are insufficient as targets as they are, but it is possible to increase the amount of reflected radio waves. By doing so, it is possible to increase the apparent radar reflection cross section and ensure the size of the target. Note that by appropriately setting the amplification factor of the amplifier 2, a radar reflection cross section of any size can be obtained. Furthermore, since projectiles such as artillery shells and rockets can be made to fly at arbitrary altitudes at high speed by setting the firing angle and flight conditions, they can be constructed as sufficient high-speed targets.

Note that the circulator 4 transfers the signal input from terminal a to terminal b.
