Emission detection circuit based on analog-to-digital signal processing of transmit-receive assembly

The invention discloses an emission detection circuit based on analog-to-digital signal processing of a transmit-receive assembly. The emission detection circuit is provided with a signal processing device, an FPGA logic control circuit, a DAC module, an ADC module, a radio frequency emission channel, a radio frequency reception channel, a transmit-receive change-over switch and a transmit-receiveantenna. On the basis of the radio frequency channel, the signal processing device used for detection control, the DAC module used for radio frequency emission, the ADC module used for detection marksignal return and the FPGA logic control circuit used for detection result judgment output are arranged, the technical problem that in the prior art, the judgment precision of successful transmissionof signals on a receiving and transmitting assembly is not high is solved. 本发明公开了一种基于收发组件模数信号处理的发射检波电路，通过设置信号处理设备、FPGA逻辑控制电路、DAC模块、ADC模块、射频发射通道、射频接收通道、收发切换开关和收发天线。本发明在射频通道的基础上，配备设置用于检波控制的信号处理设备、用以进行射频发射的DAC模块、用以进行检波标志信号返回的ADC模
