Recruit an ANA for RCS tests
Abstract
For the conduction of valid radar cross-section (RCS) measurements, it is necessary to remove unwanted signals from the test data. However, the absolute accuracy of the measurements is limited because even the most carefully designed anechoic chamber allows some residual energy to reflect from the walls, floor, and ceiling. The present investigation is concerned with an automatic network analyzer (ANA) which makes it possible to eliminate the unwanted signals from the final results on the basis of a careful calibration. The ANA system consists of a network analyzer, a swept signal source, and a test set. Attention is given to hardware choices for RCS measurements, an extension of the dynamic range, an error model, error-correction procedures for RCS measurements, and the conduction of the measurements.
