AI Technical Summary

Technical Problem

Existing technologies make it difficult to accurately measure the radiation angle of leaky cables in non-exposed spaces, especially in underground areas. Traditional microwave signal sources lack distance information, which makes measurement difficult.

Method used

A multi-channel satellite navigation simulation source is used to generate a signal containing distance information. The receiver receives signals from four satellites, calculates the pseudorange difference and corrects the transmission delay, and uses geometric relationships to solve the radiation angle of the leaky cable.

Benefits of technology

It enables high-precision measurement of the radiation angle of leaky cables in non-exposed spaces, improves the stability and uniformity of signal coverage, reduces intermodulation interference between systems, and is suitable for wireless communication channel modeling and target perception.
