s1, acquiring a state signal whether the ultrashort wave platform transmits the signal or not.
For the state signal of the ultrashort wave platform, the ultrashort wave platform can generate a state signal when the ultrashort wave platform works, the state signal can be represented by a state word '1', and the ultrashort wave platform sends the state word to the radio compass when the ultrashort wave platform works. In addition, the ultrashort wave platform also generates a status signal when its transmission is complete or not in operation, which status signal can be represented by a status word "0", which the ultrashort wave platform transmits to the radio compass when the transmission is complete or not in operation.
And S2, judging the working emission state of the ultra-short wave platform according to the state signal of the ultra-short wave platform. For example, the radio compass determines the working state of the ultrashort wave platform through a state word "0" or "1" sent by the ultrashort wave platform, that is, when the state word is "1", the ultrashort wave platform is transmitting signals, and when the state word is "0", the ultrashort wave platform signal transmission is completed or is not performed.
When the radio compass judges that the ultra-short wave radio station transmits signals, the azimuth resolving data of the radio compass changes along with the real heading/magnetic heading synchronous opposite direction to obtain changed azimuth resolving data of the radio compass.
For example, if the azimuth resolved data set of the radio compass is P (P) 1 ，p 2 ，…，p n ) True heading dataset X (X) 1 ，x 2 ，…，x n ) Then the orientation solution data set Q (Q) which changes along with the real course data set in the synchronous opposite direction 1 ，q 2 ，…，q n ) Wherein, in the step (A),
and when the radio compass judges that the ultra-short wave radio station finishes signal transmission or does not transmit signals, the azimuth settlement data of the radio compass is calculated according to a normal calculation flow.
And S3, outputting the position of the tower by the radio compass according to the processed position resolving data or the normal position resolving data.
In the method, before the radio compass calculates the azimuth calculation data, the azimuth calculation data firstly enters a calculation data smoothing filter for smoothing.
The radio compass data processing method of ultrashort wave interference provided by the application can simply, efficiently and low-cost solve the interference problem only by improving the algorithm of the radio compass without shifting the antenna of the ultrashort wave platform when the interference of the ultrashort wave platform is difficult to bear, so that the radio compass can still output correct tower azimuth when being interfered.
