Problems solved by technology

[0004] If the microwave method is used, its frequency is very high and its wavelength is very short, but its diffraction ability is very weak. Small obstacles on the ground will have a great impact on it, and the absorption capacity of the ground is also very strong, so it is generally not suitable for ground Wave propagation, using sky wave propagation, and requires a very accurate detection device to obtain the signal carried in the microwave at a long distance, so as to decipher the content. The existing long-distance microwave signal acquisition device is not accurate enough and cannot be effective. Eliminate signal interference

Description

technical field [0001] The present invention relates to the technical field of information acquisition, [0002] In particular, the present invention relates to a long-distance microwave detection device and detection method. Background technique [0003] With the rapid progress of society, radio frequency signal monitoring has a wide range of applications in many fields, such as radio frequency spectrum management, border and coastal security, wireless communication monitoring, etc. General radio uses long-wave and short-wave, long-wave, but due to the wide detection area and the need for huge antenna equipment for long-wave, my country's radio stations do not use long-wave (LW) band, on the contrary, short-wave is limited by network hubs and active repeaters, and the resistance is small. The ability to destroy and autonomous communication can be used stably, so on stable signal radio information sources, short waves or even ultrashort waves, that is, microwaves, are genera...
