Radar cross section measurement by subscale models

The paper focuses on the methodology of the RCS measurement by using radar object subscale model and on the description of the measurement facilities. The first phase of the RCS measurement by applying comparison method is the reference object (shape) design. There are some necessary conditions of the RCS calculation according to comparison method and subscale modeling. Experimental results, obtained in anechoic chamber, are also presented. Some models with scale 1:20 (typical air targets) were used for RCS measurement at the X-band and Ku-band and results were transformed for L-band.
