This article presents an extension of the classical calibration method for RCS measurements on vectorial network analyzer. The classical one [1, 2] is based on the dynamical range of the measurement system with a single reference, which causes distortion if the target return level is very low compared to the calibration reference. The new differential method uses at least two measurements of known targets and contributes a reference to the system in addition to the classical method. In addition a new dynamical scaling is developed using this technique. This is very important in the measurement of targets with a wide dynamical return range. The application of this method is compared to the existing one. ©John Wiley & Sons, Inc.
