Nearfield RCS Measurements of Full Scale Targets Using ISAR
(2014) 36th Annual Symposium of the Antenna Measurements Techniques Association p.79-84- Abstract
- Nearfield Radar Cross Section (RCS) measurements
and Inverse Synthetic Aperture Radar (ISAR) processing are
used in this study to obtain geometrically correct images and
farfield RCS. The back projection algorithm is used to determine
the amplitudes and locations for the scatterers in a point by
point imaging process. Different approximations are used to sum
the nearfield RCS recorded at an azimuthal interval of angles
when forming the farfield image. The images obtained show
the geometrically correct locations of the target scatterers with
exceptions for some target features e.g., when there are multiple
or resonance scattering features. Separate... (More) - Nearfield Radar Cross Section (RCS) measurements

are gated and an inverse processing step is performed to obtain
the farfield RCS of the full target or selected parts of the target.
Examples of images and farfield RCS extracted from simulations
and measurements on small and full scale targets using the ISAR
processing techniques described in this paper are given. (Less)
