Vol. 2 No. 1 (2016): RANCANG BANGUN SARANA UJI COATING ANTIRADAR

Since 2014 Ministry of Defense has developed a barium hexaferrite-based anti-radar material. This material will be used to coat TNI’s military vehicles. As the development has been done, it needs a testing facility to examine the material. By the existence of this testing facility, it is expected that researches on anti-radar material will be developing rapidly. The required testing facility is an anechoic chamber. The chamber is made of steel plate with a certain thickness to withstand the signal from the outside so it does not get into the room. There is also absorber in this room which serves to prevent signal reflection. Thus, the measurement can be held in ideal condition that is without any interference from outside signals or signal reflections from the measurement device. The measurements that will be carried out include Radar Cross Section (RCS). RCS measurements use a standard from the Naval Research Laboratory (NRL). The designing and developing activities result in an anechoic chamber with dimentions of 4 x 5 x 3 meters. The anechoic chamber is optimized for measurements in X-band frequency range (8.2 to 12.4 GHz). From the test results, we knew that the built anechoic chamber can be used for RCS testing for samples whose size is 5.2-70.2 cm with an accuracy up to 98%.
