Tapered resistive strip realized by patterning the constant resistive strip is used to suppress edge scattering of a flnite wedge. The suppression efiect is simulated and evaluated by the reduction in mono- static RCS (Radar Cross Section). This reduction is compared with the one which loaded by the ideal tapered resistive strip. The result indicating that patterning a constant resistive strip to create a gradient in sheet resistance is feasible. To verify this method of fabricating tapered resistive strip, patterned resistive strip with a proper gradient in sheet resistance is conducted and loaded on the wedge target for test. The gradient in sheet resistance used for test is obtained from the optimization. Resistive strip with this sheet resistance gradient renders a promising efiect of edge scattering suppression. The test result shows a reduction of 20dB for the geometric mean of mono- static RCS in the angular range of 45 - . This value is close to the one of 23dB in simulation.
