The invention discloses large power millimeter wave emission source which comprises a voltage controlled oscillator, a phase-locked loop, a frequency quadruplicating device, a first phase controller,a millimeter wave power amplifier and a second phase controller; a signal source generated by the voltage controlled oscillator serves as a reference signal; Doppler frequency modulation is carried out on the voltage controlled oscillator via the phase-locked loop so as to obtain an X-band Doppler frequency modulation signal; the frequency quadruplicating device quadruplicates the X-band Doppler frequency modulation signal to generate a millimeter wave emission excitation signal; the first phase controller ensures the wave beam and emission angle of the millimeter wave emission excitation signal; the millimeter wave power amplifier carries out pulse modulation on the millimeter wave emission excitation signal adjusted by the first phase controller to amplify the signal and further to obtain a Doppler emission signal; and the second phase controller carries out phase sensitivity control on the Doppler emission signal and emits the signal via an antenna. The large power millimeter wave emission source has the advantages including being small and mini, high in reliability and simple in debugging, and high integration of the large power millimeter wave emission source is realized.
Description
technical field [0001] The present invention relates to the technical field of millimeter waves, in particular to a high-power millimeter wave emission source. Background technique [0002] Millimeter wave (millimeter wave) refers to electromagnetic waves with a wavelength of 1 to 10 mm. It is located in the wavelength range where microwaves and far-infrared waves overlap. Therefore, it has the characteristics of two types of spectra, mainly reflected in: 1) extremely wide bandwidth: It is generally believed that the millimeter wave frequency range is 26.5-300GHz, and the bandwidth is as high as 273.5GHz. More than 10 times the full bandwidth from DC to microwave. Even considering atmospheric absorption, only four main windows can be used when propagating in the atmosphere, but the total bandwidth of these four windows can reach 135GHz, which is 5 times the sum of the bandwidths of the microwave bands below. This is undoubtedly very attractive today when frequency resource...
