本文介绍了在W波段（75至110 GHz）和J波段（220至325 GHz）的频率范围内的合成孔径雷达的碳和玻璃纤维增强塑料的冲击损伤的调查。由于碳纤维样品在两个波段中的相位延迟，有可能检测到碳纤维样品中的高能撞击。对于玻璃纤维样品，除了相位延迟之外，还可以检测幅度的变化。三维图像重建也显示了表面下的损伤。
This paper presents investigations on impact damages on carbon and glass fibre reinforced plastics with a synthetic aperture radar in the frequency range of the W-Band (75 to 110 GHz) and J-Band (220 to 325 GHz). It was possible to detect the high energy impacts in the carbon fibre samples due to their phase delay in both bands. With the glass fibre samples it was also possible to detect changes in magnitude besides the phase delay. The three dimensional image reconstruction also revealed the damages beneath the surface.
