Abstract

The invention provides an integrated frequency spectrum monitoring method for continuous waves and pulse signals, which comprises the following steps: fixed sampling: acquiring and intercepting AD data in each monitoring beat by using a fixed sampling window, performing frequency spectrum conversion, performing statistics to generate a conventional power spectrum, and performing energy monitoring on the conventional power spectrum to obtain frequency distribution parameters of the continuous signals; single-pulse trigger sampling: detecting and intercepting the pulse signal, determining a trigger acquisition moment, intercepting an effective pulse data segment, performing spectrum conversion, performing statistics to generate a maximum holding power spectrum, and performing energy monitoring on the maximum holding power spectrum to obtain a pulse signal frequency distribution parameter; and multi-scale fusion: taking the monitoring rhythm as a processing period, receiving the conventional power spectrum and the maximum holding power spectrum, and performing power spectrum correlation fusion in combination with the frequency distribution parameters to generate a composite power spectrum. According to the scheme provided by the invention, the capability of simultaneously monitoring continuous and pulse complex signals is realized.

Description

technical field [0001] The invention relates to the field of digital signal processing, in particular to an integrated spectrum monitoring method and system for continuous wave and pulse signals. Background technique [0002] Existing typical spectrum monitoring technologies take communication signals such as communication stations and satellite communications as the main monitoring objects, and have the ability to monitor and process continuous signals with high sensitivity. Since the monitoring target exists for a long time, there is no need to consider the probability of interception in the monitoring process. Therefore, in a monitoring processing cycle, a data sampling window that is much smaller than the monitoring cycle is generally used to reduce the amount of data while satisfying the acquisition of continuous signal spectrum. However, for short-duration pulse signals with low repetition frequency, the maximum intercept probability of this processing architecture is ...
