Due to the working characteristics of radar system, i.e. it has to ensure the emission and acceptance of its own radar wave,frequency selective surface(FSS) radome is the most effective stealthy way to give radome the function of frequency-selective. Combining the FSS technique and the radome together, FSS radome provides bandpass transmission properties in the operating frequency of radar, and changes the RCS characteristics of the antenna compartment when it is beyond the antenna's operating frequency ran...
