Communication method of meteoric trail communication system and conformal array antenna

Abstract

The invention provides a communication method of a meteoric trail communication system and a conformal array antenna. The method is applied to the conformal array antenna. The conformal array antenna comprises at least one conformal antenna array, each conformal antenna array comprises a plurality of patch array sub-antennas, and when a signal is received, electromagnetic wave signals respectively received by a plurality of patch array sub-antennas of the conformal antenna array are obtained, received signal preprocessing is conducted on the electromagnetic wave signals to obtain a plurality of groups of digital signals, and digital beam forming processing and demodulation processing are conducted on the plurality of groups of digital signals to obtain received signals; and when signals are transmitted, signal modulation and power division processing are carried out to obtain multiple groups of digital signals, after digital beam forming processing is carried out on the multiple groups of digital signals, transmitted signal preprocessing is carried out to obtain transmitted signals corresponding to each patch array sub-antenna, and the signals are transmitted through the patch array sub-antennas of the conformal antenna array. According to the invention, the convenience, gain and application range of the meteoric trail communication system are improved.

Description

technical field [0001] The invention belongs to the technical field of meteor trail communication, and in particular relates to a communication method and a conformal array antenna of a meteor trail communication system. Background technique [0002] Meteors will emit a lot of light and heat when they pass through the sky, which will ionize the surrounding gas, and quickly spread to form a columnar ionized cloud centered on the meteor track. This ionized cloud has the characteristics of reflecting radio waves. This is the so-called "meteor trail". Long-distance communication using meteor trails to reflect radio waves is called meteor trail communication. [0003] In the meteor trail communication system, commonly used antennas include Yagi antennas and logarithmic periodic antennas. Due to the low communication frequency band of the meteor trail communication system, the size of the antenna is large. When the required antenna gain is high, the length of the antenna will be...

AI Technical Summary

Problems solved by technology

Due to the low communication frequency band of the meteor trail communication system, the size of the antenna is large. When the required antenna gain is high, the length of the antenna will be larger, which increases the difficulty of antenna erection and reduces the cost of the meteor trail communication system. The convenience of use greatly limits the application scenarios of the meteor trail communication system, making the meteor trail communication system only for fixed use or vehicle-mounted transportation.
