Abstract

Presents the development results of a device for defect exposure in flaky multi-layer fiber-glass plastic structures (e.g. airborne radomes) and polymeric and lacquer-and-paint protective coatings. A defects disclosure criterion is based on the analysis of amplitude and phase parameters of incident and reflected waves with the use of special algorithm in non-defect and defective materials. The range of working frequencies is 53...62 GHz. The device consists of two blocks: SHF sensor and microprocessor unit with LCD-indicator. Power supply: 220 V, 50 Gz (or 22...32 V DC), 8 W.
