The invention discloses a low-frequency time code time service
signal carrier frequency optimization method and
system, and the method comprises the following steps: carrying out the first screening of frequency points based on a preset antenna effective
radiation power threshold value, and obtaining a first
screening result; carrying out the second screening of the frequency points based on the in-band interference factors, and obtaining a second
screening result; carrying out the third screening of the frequency points based on the
sky-ground wave interference characteristic factors, and obtaining a third
screening result; based on the first screening result, the second screening result and the third screening result, carrying out screening according to
frequency generation factors to obtain a final screening result, and completing the low-frequency time code time service
signal carrier frequency optimization. According to the method provided by the invention, the low-frequency time code time service
signal carrier frequency meeting the preset requirement can be selected.
