FIR photometry (from 15µm to 200µm) of NGC 3079 which is resolved by ISOPHOT at 60µm is presented. With the assumption of an unresolved core plus an extended disk component, good consistency with IRAS and SCUBA data is found. The SED of the total flux between 60µm and the submm can be modelled by the superposition of three dust components with temperatures of 32K, 20K and 12K. The emission of the extended disk component is 1/3 of the unresolved core component in the 60-180µm range, from 200µm onwards its relative contribution increases. The resulting dust mass of 3.8x10⁷M_☉ is consistent with a total gas-to-dust mass ratio of 200, close to the canonical value found for the Milky Way. These results demonstrate an appropriate way to disentangle and characterize the main dust components by combining ISOPHOT FIR data from the ISO Data Archive with submm data from SCUBA.
