The accident of a fishing vessel hit by a larger merchant ship has been quite common in Indonesia. It is because the large vessels failed to detect the fishing boats clearly, which was exacerbated by the absence of passive radar reflector on-board. The previous study found that the attempt to introduce passive radar reflector to local fishing communities need to consider the design of the radar reflector in harmony with the ornamentation found on local fishing boats. Based on the above issue, the passive radar reflector that adopts the ornamentation on local traditional fishing vessels has been designed and tested. The standard octahedral passive radar reflector was covered by casing in the form ofMosque dome made of fiberglass reinforced plastic as an adaptation of local culture. The test showed that there is a slight difference on the performance of passive radar reflector with and without FRP casing.
