METHOD AND APPARATUS FOR MEASUREMENT OF RADAR CROSS- SECTIONAL AREA, AS WELL AS RECORDING MEDIUM WITH THEIR RECORDED CONTROL PROGRAM RECORDED THEREON

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for the measurement of radar cross-sectional area, wherein the radar cross-sectional area at a distant place can be obtained even when the phase of a scattering electric field is hard to measure, and to provide a recording medium on which their control program is recorded.;SOLUTION: In the measuring method for the radar cross-sectional area of a specimen which is large in the horizontal direction and which is sufficiently small in the vertical direction when considered on the basis of a measuring condition in the distant region of the radar cross-sectional area, the measured value of the amplitude of the scattering electric field measured in such a way that the specimen is rotation-scanned or rectlinear-movement-scanned in at least two positions 1, 2 whose distances from the specimen within a neighboring region from the specimen 1 are different is converted, and the radar cross-sectional area in the distant region is found.;COPYRIGHT: (C)2002,JPO
