The utility model discloses a receiver with the function of linearly indicating the level intensity, relating to a receiver which can linearly indicate the level for estimating the communication distance in the communication field. The receiver comprises a C wave band mixing module, an L wave band electromodulation module, an L wave band mixing module, an intermediate frequency electromodulation module, a main amplification module, a demodulation module, and the like. The receiver completes the transmission of C wave band radio frequency signals to intermediate frequency signals for the communication between a fixed station and a moving target, can linearly indicate the level intensity of the signals while completing the information transmission, estimates the communication distance between two points through the level indication, and ensures that the signals sent to a terminal demodulator is enough strong and is stable within a certain range. The utility model has the advantages of convenient application, low cost, small volume, light weight, high reliability, convenient maintenance, and the like, and is especially suitable for a system having the control demands on the moving object to be used as the receiver.
