All the things from gun mounts to antennas, deck lockers and helicopter hangers will have a radar cross part. The RCS of each of these should be minimized as much as feasible. Just one deck ingredient without having a small RCS can render other RCS reduction attempts redundant. Mr. Boy calls this a “flashlight result” wherever one part can strongly replicate a radar signal and risk betraying the ship. One can observe in modern styles similar to the VISBY and ZUMWALT courses the endeavours taken to cut back the level of superstructure clutter. Capt.

As an example, an X-band frequency of 8.5GHz may have a wavelength of 35.2mm. Fifty percent this wavelength is seventeen.6mm. Chaff dipoles would need for being this duration to jam a radar transmitting on 8.
