Multi-order adaptive signal large dynamic receiving method

The invention discloses a multi-order self-adaptive signal large dynamic receiving method, which belongs to the field of electronic countermeasure, and comprises the following steps of: firstly, constructing two multi-stage gain fusion units selected by switches, respectively comprising one path of N-path coupling cascade amplification channels and one path of M-stage coupling cascade attenuation channels; judging whether the signal is input into the N-stage amplification channel or the M-stage attenuation channel, and calculating the gain or attenuation required by output according to the signal amplitude; calculating a noise coefficient and cascade propagation loss of a signal channel; and then the attenuation coefficient of actual work is solved through the intelligent feedback network. And finally, the multi-stage gain fusion network adaptively feeds back the gain multiple, namely reversely controls the gain and matches the output level. 本发明公开了一种多阶自适应的信号大动态接收方法，属于电子对抗领域，首先构建两路由开关选择的多级增益融合单元，分别包含一路共N路耦合级联放
