1, CO 2 laser Doppler radiated by the heterodyne receiver can be used as a target positioning and missile guidance system. The light emitted by the positioner immediately follows the target after it has been captured and provides a signal identifying the carrier and enemy. It also serves as a marker for the missile's guidance of the light beam and the target. 2. In the system according to Digest 1, the initial flight section of the locator beam-guided missile, the target tracking flight section, is controlled by the head of the infrared target seeker, which receives the modulated laser radiation from the locator beam. 3. In heterodyne reception using a homodyne or heterodyne detector in systems conforming to Digest 1 or 2. 4. In a system as claimed in any one of the foregoing abstract numbers 1 to 3, the transmitter comprises a frequency stabilized CO 2 waveguide laser comprising a modulator and an optical transmitting means, and a controller associated therewith An IFF device. The receiver contains an optical detection system, a beam splitter, a modulator (the necessary laser beam shift for homodyne reception), and a beam mixer. The reflected portion of the positioning and guiding beam is mixed with the transmitted beam by the mixer and input to the detector. The signal output by the detector is transmitted to the computing device to determine the azimuth, elevation, distance and motion of the target, It is also sent to the IFF receiver. After the signal entered the controller and tracking calculator, it linked the missile to the guidance system. 5. From the point at which the device is required to comply with the Summary 4, a laser local oscillator can be used instead of the splitter and modulator. 6. In devices that comply with Summary 5, there is a fixed and well-defined frequency difference between the local oscillator and the main laser. 7, for the target acquisition and guidance system Guided missile components and assembly methods basically as shown in the figure, for reference. 8. The construction and assembly method of the device for guiding the missile to the target are basically as shown in the accompanying drawings for reference.
