Abstract

PURPOSE:To get a long range distance and provide a characteristic for all- weather conditions by a method wherein a reflected electromagnetic wave radiated from a self power generating fan and a transmitter installed in a master bullet toward a target is caught and followed by a slave bullet so as to perform a semi-active guide control. CONSTITUTION:A master bullet 1 flying toward a target 13 ejects a slave bullet 9 at a predetermined position, then a self-power generating fan 4 is rotated by an air resistance dropping and the self-power generating operation is carried out and the master bullet 1 drops at a slower speed than the slave bullet 9. The master bullet 1 uses a generated power and radiates an electromagnetic wave 14 toward the target through a transmittance device 3. The master bullet 1 itself follows the target 13 through an active homing action and a the same time the slave bullet seeking device 9 may also receive the reflection wave 15 from the target 13, catch the target 13 and follow it. With such an arrangement, it is possible to get a semi-active homing guide method so as to adapt a long range and all-weather conditions.

(Problem that Hakumei is trying to solve) The conventional method of searching and changing the tail of a parent-child guided flying vehicle is as described above. Equipped with a transmitter to activate
Radar - Achieving homing guidance It is difficult to operate due to the large size of the bullet and the high cost.Passive homing guidance passively receives the electromagnetic waves radiated from the target. Method K is limited and has a short range. Captured in the rain. This invention had problems such as a decrease in tracking ability. This was done to solve the problems mentioned above. Guidance control of submunitions l. [One method is passive
Aiming at obtaining a semi-active homing guidance method that has a long range and all-weather performance that cannot be obtained with the homing guidance method (Means for Solving the Problem) How to defeat it.
Equipped with a transmitter inside the parent bullet to slow down the relative falling speed of the parent bullet after ejecting the sub-bullet. [Sakuwa] The guidance control method in this invention makes it possible for the parent bullet to be positioned behind the target as a result of the irradiation of the sub-munition's sea force. In contrast, place the sub-munition behind the sub-munition to slow down its relative falling speed with the sub-munition, and direct it from the transmitter inside the parent munitions to the target? ! ! Illuminate him. The submunition sea force captures and tracks him as it is reflected from the target.

[Effects of the Invention] As described above, according to the present invention, the base missile 1 is equipped with the transmitter 4. However, after the submunition is released, the parent munition receives some of the force generated by its own power generation from the rear of the submunition and continues to hit the target, so the submunitions' semi-active guidance @
It is possible to shoot for a long time. It will have the effect of providing all-weather resistance.
