Method and device for resisting forwarding interference

The invention discloses a method and device for resisting forwarding interference. The method comprises the steps of: constructing a sparse model of an echo signal according to the constructed echo signal under phase coding, carrying out compression observation on the sparse model, and constructing a compressed sensing model according to an obtained compression observation result; calculating a matched filtering result of the echo signal under the phase coding and an intermittent sampling interference signal; and providing an estimated value for the compressed sensing model through the matched filtering result, and identifying n interference pattern according to the compressed sensing model. According to the method, the interference signal estimated value is provided for the compressed sensing model under the phase coding through the matched filtering, so that a phase coding system radar has identifying ability for forwarding interference signals. 本发明公开了一种抗转发式干扰方法及装置，所述方法包括：根据构建的相位编码下的回波信号，构建所述回波信号的稀疏模型，并对所述稀
