Super High Frequency (SHF) Link Analysis Model (SLAM) for Nonsatellite Applications
Abstract
A point-to-point link analysis model has been developed for the Super High Frequency (SHF) Band. It was developed to evaluate ship-to-ship and ship- to-air links. The SHF Link Analysis Model (SLAM) evaluates a communication link and determines system margin. The link margin is determined after a user defines the transmitter subsystem, the receiver subsystem, the specified level of system performance, and the propagation channel. The propagation channel incorporates the Engineer's Refractive Effects Prediction System (EREPS) and includes the effects of the evaporation duct. A rain model developed by NASA is also included in the channel. SLAM provides a detailed discussion of the link equation, the propagation effects, the rain model, and the antenna characteristics. In addition, a detailed explanation of the operation of the SLAM computer program is given. Two communication links are evaluated and these examples are used to demonstrate the computer program's capabilities.
