Development of Microwave Absorbes for X-Band RADAR

X-밴드 레이다용 전파흡수체의 개발에 관한 연구

Microwave absorbers for X-Band RADAR have been designed and fabricated trialy both in sheet and paint types, as a result of which the relative bandwidth of nearly 8% in both cases has been obtained under the tolerance limits of the reflection coefficients lower than -20dB. The matching thickness becomes 1.36 to 1.56mm which is significantly thinner than that of the conventional ones. Furthermore, it was shown that the microwave absorbing characteristics vary in accordance with the density and the mixing ratios of the materials constituting absorbs.
