RF Exposure Evaluation Report 1. Product Information ManufacturerFuruno Electric Co., Ltd. 9-52 Ashihara-cho, Nishinomiya city, Hyogo, 662-8580 Japan Trade nameFuruno TypeRTR-136 ModelTransceiver for RADAR SENSOR DRS4DL X-Class Product DescriptionShip radar station operating in the band 9300–9500 MHz FCC IDADB9ZWRTR136 Frequency Range9380MHz ~ 9440MHz Peak Envelope Power (PEP)4kW Antenna Gain (G p )21.5dBi Beam Width (θ)5.2° Maximum Pulse Width (τ) 0.8μs Pulse Repetition Frequency (PRF) 360Hz Minimum separation distance0.73m 2. Evaluation method and Limit FCC requirements According to FCC CFR 47 part1 1.1307 (b)(3)(i)(C): The criteria listed in the following table shall be used to determine the exemption of further evaluation. R is the separation distance and is 0.73m instructed in the installation manual. Threshold ERP * is ERP TH = 19.2 × 0.73 2 = 10.23 [W] * ERP: refer to FCC CFR 47 part1 1.1307 (b)(2) 3. Evaluation Results Calculated ERP ERP = PEP × 10^ቆ G p −2.15 10 ቇ× ( τ× PRF ) × θ 360 ERP = 4000 × 10^൬ 21.5−2.15 10 ൰× ( 0.8 × 10 −6 × 360 ) × 5.2 360 = 1.43 [ W ] ≤10.23 [ W ] where: PEP is converted to the mean power using the pulse width and the pulse repetition frequency. G p is converted to a gain relative to a dipole. The antenna rotates continuously over 360 degrees in the horizontal plane and illuminates the subjects only by its main lobe. Therefore, time-averaged power is derated by the beamwidth and the angle of rotation.
