    • PROBLEM TO BE SOLVED: To provide a target tracking guidance device and its method, constituting a system without mounting a laser output adjusting device and the like, since the reflected light of stable intensity is detected by a seeker regardless of angles of a laser irradiator, a target and a flying object, suppressing increase in dimension and mass of the laser irradiator, and eliminating restriction in operations such as transportation and installation. SOLUTION: This target tracking guidance device includes: a laser beam irradiating device 12 for irradiating the laser beam 3 to the target 1; and the flying object 14 loading the infrared ray seeker 16 detecting the reflected light 4 of the laser beam by the target, the laser beam 3 is irradiated to the target, and the reflected light 4 is detected by the infrared ray seeker 16, thus the target is captured, and the flying object is made to fly toward the target direction. A polarized light converting element 18 (1/4 wavelength lagging element) is disposed to convert the polarized light of the laser beam 2 generated by the laser beam irradiating device 12 from the linear polarized light to the circular polarized light, and the polarized light of the laser beam is converted from the linear polarized light to the circular polarized light to irradiate the laser beam 3 of circular polarized light to the target.

    • PROBLEM TO BE SOLVED: To improve positioning accuracy in a passive type missile observing TDOA and FDOA and passively positioning a target position. SOLUTION: This passive type missile flight control device observes the TDOA and FDOA by receiving both scattered waves irradiated from a known transmission source, made to hit a target and scattered and direct waves directly coming from the known transmission source, and includes a flight control part (14) positioning the target without irradiating electric waves and controlling its own flight route toward the target. The passive type missile flight control device further includes a GDOP calculating part (18) calculating GDOP based on the geometric arrangement of the missile, the transmission source and the target, estimating the orthogonal degree of ISO-TDOA and ISO-FDOA and generating a quantitative determination index of current measurement errors by the missile.
