| Abstract(in English) | When the scattering pattern of radar cross section (RCS) is measured, the characteristic is usually evaluated in the far-field area. In that case it is measured in the radio anechoic chamber to reduce unnecessary reflected wave and likely to deviate from the condition of the far-field according to the size or the measuring frequency. On the other hand, it is well known the method such as compact-range or the transformation processing method to the far-field from the pick-up near-field data. In this paper, it is presented an improved approach to determination of RCS of electrically large targets from the scattered field measured with a monostatic radar over a circle in the near-field of the targets. The frequency- and azimuth-domain scattering data are used to calculate a radar reflectivity map of the target, from which RCS of the target is determined. The characteristic features of the proposed version of Near-Field-to-Far-Field Transformation (NFFFT) are the use of the calibrated signal from the network analyzer as the input data in the transformation and an improved focusing operator for producing reflectivity maps. |
