In this research, various methods for camouflage against radar equipments have been introduced. Based on this idea, the radar absorbing mechanism has been studied with emphasis on the single layer structure mechanism (Salisbury screen) with a resistive sheet. The Salisbury screen is a resonant absorber created by placing a lossy sheet on a low dielectric constant spacer in front of a metal plate forming one layer structure. Fabric structure of the resistive sheet was accurately chosen and coated with lossy material. In fact, many absorbing materials are manufactured with lossy materials providing the loss mechanism, and the dissipation of energy takes place by the conversion of electromagnetic energy into heat. Lossy mechanism may be carbon or dielectric materials with complex indices of refraction. Lab measurements have been done to get optimum formulas and optimum fabrics structures for high radar absorption performance. Various textiles including plain woven fabrics and spacer fabrics was utilized to study the construction of X and Ku band radar absorbent coating. Carbon black and carbon nano tube as conductive materials were used for coating of fabrics. In addition, the effect of metal powders such as copper and aluminum on the absorber performance was studied. In this research, after printing experiments, various formulas of lossy materials which had suitable printing properties and more conductivity have been chosen and studied as material type parameter. Printing techniques was used to coat the samples on three types of plain woven fabrics in the radar absorbent structure. The e ff ect of parameters such as lossy material type, lossy material thickness, spacer fabric thickness and coated fabric material on the electromagnetic waves absorption at bandwidth 8-18 GHz was investigated. Taguchi method was used to optimize costs and the number of radar absorption experiments as well as statistical and systematic analysis of the results. From analyze of variance, the findings reveal that the material type and spacer fabric thickness are two parameters which statistically have significant influence on the results of experiments.

In addition, at 8-15 GHz bandwidth, the samples able to absorb 90 percent of electromagnetic waves and at bandwidth 9.3-12.5 GHz, the samples were able to absorb 97 percent of the waves.
