A series of conductive coatings with different resistivity were synthesized by using waterborne polyurethane as binder and chopped carbon fiber as conductive filler. The effect of carbon fiber in conductive coating on surface resistivity, radar transmission, and RCS was studied. By adjusting the content of carbon fiber, the RCS of shape camouflage bait can be controlled. The results showed that conductive coating has excellent radar reflection characteristics, and can be used in controlling fake target RCS in equipment camouflage field, electromagnetic shielding in composite materials packing box, and anti-electrostatic packaging needs of equipment.
