<p><P>PROBLEM TO BE SOLVED: To improve positioning accuracy in a passive type missile observing TDOA and FDOA and passively positioning a target position. <P>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. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
