The invention belongs to the technical field of ultra-short wave channel receivers and discloses a ultra-short wave channel receiver with high dynamic range. Based on the architecture of superheterodyne quadratic frequency conversion, the reveiver comprise a RF proces module, a first mixer, a first intermediate frequency processing module, a second mixer, a second intermediate frequency processingmodule, an AGC control amplification module and a digital signal processing module. It can be ensured that the signal distortion is smaller, the bit error rate is lower, the adaptability of the receiver is larger, and the anti-interference ability is stronger, so as to meet the high dynamic range of the whole channel receiver 120dB. 本发明属于超短波信道接收机技术领域，公开了种高动态范围的超短波信道接收机。采用超外差二次变频的体系结构，主要由射频处理模块、第混频器、第中频处理模块、第二混频器、第二中频处理模块、AGC控制放大模块、数字信号处理模块组成，能够保证信号失真更小、误码率更低，使接收机的适应度更大、抗干扰能力更强，从而满足整个信道接收机120dB的高动态范围。
