Abstract: Localization technique for space debris impacted typical spacecraft protection structure with PVDF sensors is studied in theory and test. The structure types including aluminum plate, curved aluminum plate and Whipple shield are studied to verify the applicability of this localization technique. The localization method based on hyperbola theory is investigated. The hyperbola localization theory is validated by the test of air rifle and hypervelocity ballistic range. The velocity range of the projectile is from 100m/s to 3km/s. The structure types investigated are aluminum plate with thickness of 2mm and Whipple shield with 10cm distance between front and rear wall with thickness of 1mm. Analysis shows that the localization technique based on PVDF sensor in this study is proved to be applicable to detect the position of typical spacecraft protection structure impacted by space debris.
