Description

technical field [0001] The invention relates to the field of test analysis, in particular to a pulse sequence signal correlation analysis and display system, and also relates to a pulse sequence signal correlation analysis and display method. Background technique [0002] With the development of military electronic system technology, pulse modulation signals in radar and other system equipment are becoming more and more complex, and the characteristic parameters of signals are also increasing. The characteristics of various parameters of the pulse signal reflect various performance indicators of the system equipment, such as pulse width determines the distance resolution, pulse repetition frequency determines the fuzzy distance, linearity, frequency modulation bandwidth, etc. are used to measure the quality of pulse compression signals. [0003] At the same time, due to the larger internal memory capacity of data acquisition and analysis platforms such as modern signal analy...

[0004] Therefore, the existing single-pulse single-parameter analysis and display method has few test parameters, lacks correlation analysis, cannot provide parameter change information and rich graphic information, and can no longer meet the testing requirements of complex pulse sequences. The pulse sequence data must be analyzed. Contrastive correlation analysis, analysis and display of various parameters of the pulse, investigation and analysis of information such as parameter changes inside and between pulses of the radar pulse signal, so as to locate abnormalities or failures of components at different positions in the signal path, which is helpful for in-depth understanding of the signal in the signal path.
