Problems solved by technology

[0005] 1. It is difficult to meet the flexible switching monitoring requirements of weak signals and high-power signals in different scenarios
When the active antenna of the system is working, encountering a high-power signal may easily cause system saturation or even burn out, and the user must replace the antenna with a small gain
[0006] 2. The system switch matrix only has the function of antenna frequency band switching, and cannot realize antenna power supply and status control
[0007] 3. The battery life of the active antenna power supply is limited and needs to be replaced regularly
[0011] 2. In view of the problem that the switch matrix of the traditional monitoring system only has the function of antenna switching and cannot meet the needs of antenna power supply and state control, a reconfigurable switch matrix design method is proposed, which can not only switch antennas in different frequency bands but also realize multi-antenna power supply
