Beschreibung
Zusammenfassung:	The invention discloses a method and device for resisting spectrum dispersion interference. The method comprises the steps of: constructing a first sparse basis matrix of an LFM echo signal, constructing a second sparse basis matrix of a spectrum dispersion interference signal, constructing a joint sparse basis matrix according to the first sparse basis matrix and the second sparse basis matrix, reconstructing the LFM signal according to the joint sparse basis matrix; optimizing an interference parameter based on a first interference parameter estimation value to obtain a second interference parameter estimation value, recalculating the second sparse basis matrix based on the second interference parameter estimation value, and setting the second interference parameter estimation value as the first interference parameter estimation value for next interference parameter optimization; and determining a termination condition for optimizing the interference parameter, if the termination condition is met, outputtin
