Naval weapons center plume radar frequency interference code

A description of the Naval Weapons Center Plume Radar Frequency Interference Code (PRFIC) is given. The methods used to predict the attenuation and phase shifts contributed by the mean plume flowfield, and the scattering and Doppler shift due to turbulent fluctuations, are defined. Examples of the predictions of the plume RF interference using the flowfield predictions of a modified JANNAF Standard Plume Flowfield code are given. The capabilities and limitations of PRFIC are listed and improvements are proposed. A code user's manual and software description are included.
