Automatic link establishment (ALE) is one of the important technologies in HF communication. One of the indicators to measure the performance of an ALE system is the linking time, which includes channel switching, spectrum sensing, and trying to call three periods. Asynchronous mode has been widely used for its simple operation. When establishing an link, the station sorts all the channels and selects...
Gain and phase errors sensitivity is an issue common to all high-resolution direction-of-arrival estimators. In this paper, we first provide the conventional and improved data models. Second, based on the conventional data model, an algorithm called estimation algorithm for the conventional data model (EACDM) is proposed to estimate the gain and phase errors existing in the sensor array for the uniform...
