METHOD OF ESTIMATING EQUIVALENT RADAR CROSS SECTION ON THE BASIS OF NEAR-FIELD MEASUREMENTS

摘要

The present invention relates to a method of estimating equivalent radar cross section (RCS) of an object with the aid of near-field measurements, the method using a model of far-field diffraction of the object and a model of near-field diffraction. These models make it possible to determine respectively bases suited to said object for far field and for near field. The vector of measurements is firstly projected onto the basis suitable for near field and the components obtained are transformed into components on the far-field basis. The vector obtained is then reduced to the RCS analysis basis to provide a reconstructed vector. The components of the reconstructed vector are then used for the calculation of the RCS. The invention also relates to a computer program for implementing said method of estimation.
