The invention discloses an automatic calculation method about loran
signal integrity, and the method comprises the steps: outputting a first
simulation loran pulse oscillogram through a conventional
receiver, carrying out the preprocessing of the first
simulation loran pulse oscillogram, and obtaining a second
simulation loran pulse oscillogram; inputting the second analog loran pulse oscillogram into a digital recorder for DA acquisition; collecting data collected by the digital recorder to obtain a data
list, finding data of # imgabs0 # and # imgabs1 # in the data
list through automatic calculation, and then calculating
effective power to obtain a final result; theoretical waveform parameters are calculated through data of # imgabs2, theoretical waveform data and collected data are compared, and a waveform integrity result is obtained.
Data analysis is carried out on the improved waveform, a
data point of # imgabs3 is determined in real time, when # imgabs4 is collected in real time, the
effective power of the waveform can be calculated through a formula, and post-
processing is not needed; and similarly, when # imgabs5 # is acquired, the
signal integrity can be analyzed in real time according to a formula.
