CALCULATION OF SIGNAL-TO-NOISE RATIO FOR HF PROPAGATION PREDICTION.
Abstract
Calculation of signal-to-noise ratio for operational sky-wave modes at high frequency is described. The process applies to a computer program written in NELIAC 5M for the CDC 1604. Calculation includes factors of field strength, antenna gain, signal voltage, and noise. Noise data used are based on CCIR Report No. 65. Configurations for most hf antennas, including log periodic, are provided for. Means are provided for comparing NEL and CRPL program results. The NELIAC 5M program is presented in NEL Report 1358 (AD-633 716). Selection of operational modes is covered in NEL Report 1364 (AD-633 893). (Author)
