Fast algorithm for the exact determination of the mapped effective areas of trihedral radar reflectors

There is currently interest in the use of trihedral radar corner reflectors as ground targets for the calibration of synthetic aperture radars and scatterometers carried by remote sensing satellites. Keen (1983) has described a new technique for the evaluation of the scattering cross-sections of radar corner reflectors. This method, which uses computer evaluation, is briefly discussed. On the basis of new experience related to the employment of the scattering cross-section prediction method, a more efficient and exact way for carrying out the evaluation of mapped effective areas has been developed. The present investigation is concerned with this alternative technique.
