The invention provides an active microwave source combination. The active microwave source combination comprises a frequency synthesizer unit, an up-conversion unit, a transmitting unit, a receiving unit, and a power supply and control unit; the frequency synthesizer unit generates a crystal reference signal, a crystal reference coupling signal, a local oscillator signal and an output signal needed by the whole machine, and generates a first local oscillator signal and a second local oscillator signal needed by the up-conversion unit and the receiving unit; the up-conversion unit completes twotimes of up-conversion of an input intermediate frequency, and pre-modulates the signal after the first up-conversion under the action of a pre-modulating pulse; the transmitting unit performs amplification and coupling on the output signal of the up-conversion unit and divides the power into four channels, wherein one channel outputs a self-calibration signal through the input square wave signalswitching modulation and
