| Abstract: | Along with the development of electronic technology and extensive application of all kinds of wireless transmitting devices, various unexpected electronic interferences are encountered in wireless receive devices, especially in high sensitive radar. Having experienced several electronic interference events,, some typical cases are selected, such as the co-frequency interference between weather radars, the co-frequency interference between weather radar and military radar, as well as interferences from microwave relay stations and civil UHF transmitters. The electronic interference phenomenon and the detecting process are introduced, and the formation causes and practical solutions are discussed. |
| Keywords: | radar co-frequency interference higher harmonic spectrum analyzer |
