Radar Cross Sections of Surface Ships at Grazing Incidence

Abstract

The radar-cross-section (RCS) values of seven classes of surface ships have been determined at grazing incidence at frequencies of 1300, 2800, and 9225 mhz for horizontal polarization and for vertical polarization at 9225 mhz. Measurements were performed at the Chesapeake Bay Division at NRL as the ships proceeded in a circular orbit. The ships used for the measurements were the DD 764, DEG 6, DDG 19, LPD 1, DE 1027, DLG 26, and AFS 5. In addition, measurements were made on the DLG and AFS in C band at 5500 MHz for both horizontal and vertical polarizations. Cross-section values were plotted as a function of ship aspect in the form of polar profiles. The profiles plotted were the 20, 50, and 80 percentile values of the RCS distribution function, which were determined for 2-degree azimuth increments.
