Abstract
In response to the requirements for efficiency, accuracy and safety of shock wave testing, a wireless shock wave overpressure test system was developed by using 4G wireless communication technology and storage testing methods. A study on the transmission performance of ground antennas was carried out, and a free-space modified model was established, which characterizes the relationship between the reference signal received power PRSR and any transmission distance L. The experiment results show that the theoretical value is in good agreement with the experimental value, and the PRSR decreases with the increase of L. Within a certain range, the ground influence factor ω decreases with the increase of the antenna height at the receiving end, the free space transmission path loss LF decreases and the PRSR increases accordingly.
