AI Technical Summary
Existing methods for calculating the interference radius of mobile communication jammers suffer from problems such as large interference in the test environment, insufficient adaptability to the scenario, and unreasonable selection of core indicators in real-world scenarios. These issues result in large errors in the calculation results and make them unsuitable for extreme communication environments.
A simulated communication link is constructed in a microwave anechoic chamber. Carrier interference noise ratio (CINR) is used as the core indicator. Combined with the downlink signal parameters of the base station at the target deployment location, a quantitative relationship between the interference radius and CINR is established. The interference radius is calculated by setting the mapping relationship between the distance D between the jammer under test and the receiving antenna and the carrier interference noise ratio in the microwave anechoic chamber.
It improves the accuracy and engineering guidance value of interference radius measurement, can adapt to base station signal environments of different intensities, ensures that the measurement results are consistent with the actual interference effect, and provides scientific guidance for jammer deployment.
