AI Technical Summary

Benefits of technology

This patented technology helps predict if an antenna system will work well over different frequencies based upon its own characteristics such as signal strength and weather conditions during use. It also allows for quicker and more precise determination of operational frequency values than current techniques like radioactive probes. Additionally, it addresses issues related to long distance transmission due to interference from signals transmitted along multiple paths simultaneously. Overall, this new technique makes better understanding how electronic devices operate and improve their overall performance while being used outdoors without experiencing adverse environmental factors affecting them's ability to communicate wirelessly.

Problems solved by technology

The technical problem addressed by this patented method relates to accurately predicting the properties of radioactive materials within specific regions called ionospheroids during long distance communications between satellites without relying solely upon measurements from these areas alone. Current techniques are limited because they only provide qualitative indicators such as timing delays associated with different types of atmospherics at certain times.

Abstract

The invention relates to a short wave communication reliability evaluation method based on multi-system detection data. The method comprises the steps of: calculating reflection point positions of a short wave communication link and all detection links, and selecting detection link data close to the reflection point position of an ionized layer of the short wave communication link; according to the determined reflection point positions of ionized layers of the detection links and the determined detection link data, forecasting an ionized layer parameter of reflection points of the ionized layers of the detection links; according to the determined reflection point positions of the ionized layers of the short wave communication link and the detection links and the forecasted ionized layer parameter of the reflection points of the ionized layers of the detection links, reconstructing an ionized layer parameter of the reflection point of the ionized layer of the short wave communication link; forecasting the highest available frequency of the short wave communication link by using a short wave propagation forecasting method according to the obtained ionized layer parameter; and calculating the received field intensity when the short wave communication link adopts the highest available frequency for communication according to the obtained highest available frequency, and analyzing the reliability of the short wave communication link.
