<p><P>PROBLEM TO BE SOLVED: To provide a method of suppressing glint noises during radio wave guidance and its device, avoiding such inconveniences in a conventional method of suppressing noises using a lowpass filter that a cut-off frequency for reducing guide signal noises cannot be uniformly determined to possibly cause the degradation of guiding accuracy to develop trouble in guiding a trajectory structure requiring high responsiveness. <P>SOLUTION: The device comprises a data accumulation processing part for storing a viewing line error angle on which a dispersion is superimposed, a distribution gravity center error angle computation part for statistically processing storage data in selective numbers, calculating a data dispersion distribution gravity center and calculating a distribution gravity center error angle from the distribution gravity center and a beam center point, and a seeker gain multiplication part for multiplying the distribution gravity center error angle by a seeker gain to form a guide signal. Thus, the guide signal is computed from the distribution gravity center error angle with suppressed noises of the viewing line error angle and has suppressed glint noises, so that it can be guided with high accuracy and high responsiveness to meet a high- speed and high-turning-performance target in a well precise manner even when there is a small relative distance between the target and a radio wave guide. <P>COPYRIGHT: (C)2004,JPO</p> |
