[0050] The output end of the first radio frequency power divider 2 is connected to the electrical input end of the first radio frequency optical transceiver component 9 .

[0051] The optical output end of the first RF optical transceiver component 9 is connected to the optical input end of the second RF optical transceiver component 10 through an optical fiber optical path, its optical input end is connected to the optical output end of the second RF optical transceiver component 10 through an optical fiber optical path, and its electrical output end is connected to the third input end of the pulse phase measurement module 7.

[0052] The electrical output end of the second radio frequency optical transceiver assembly 10 is connected to the input end of the digitally controlled phase shifter 4 , and the electrical input end is connected to the output end of the single-pole double-throw switch 6 .

[0053] The output end of the second RF power divider 3 is connected to the second input end of the pulse phase measurement module 7 .

[0054] The output end of the digitally controlled phase shifter 4 is connected to the input end of the one-to-two power divider 5 .

[0055] The first output end of the one-to-two power divider 5 is used to connect to the input end of the phased array high-power microwave system to be tested, and the second output end of the one-to-two power divider 5 is connected to the first input end of the single-pole double-throw switch 6 .

[0056] The second input end of the single-pole double-throw switch 6 is used to connect to the output end of the phased array high-power microwave system to be tested;

[0057] The pulse phase measurement module 7 includes a digital acquisition processor 71 and N down-conversion channels 72;

[0058] The N first input ends of the N down-conversion channels 72 are respectively connected to the N output ends of the second RF power divider 3, their second input ends are connected to the electrical output end of the first RF optical transceiver component 9, and their output ends are connected to the second input end of the digital acquisition processor 71; the first input end of the digital acquisition processor 71 is connected to the third output end of the reference frequency generating module.

The single-pole double-throw switch (6) loops back the N first excitation signals and sends them to the second radio frequency optical transceiver component (10), or sends the N microwave pulse signals generated by the N high-power microwave generating units being excited by the N second excitation signals to the second radio frequency optical transceiver component (10); 4.

2. The second radio frequency optical transceiver component (10) receives N microwave pulse signals or N first excitation signals and performs electro-optical conversion to generate N second optical signals and sends them to the first radio frequency optical transceiver component (9); 4.

3. The first radio frequency optical transceiver component (9) receives N second optical signals, performs photoelectric conversion on them, and then converts them back into N microwave pulse signals or N first excitation signals and sends them to the pulse phase measurement module (7).

7. The phase control method for a phased array high power microwave system according to claim 6, characterized in that: Step 5 specifically includes: 5.

1. N down-conversion channels (72) pass through frequency f c +f IF The down-converted local oscillator signal converts N microwave pulse signals into N channels with a frequency of f IF The intermediate frequency pulse signal, or through the frequency f c +f IF The down-converted local oscillator signal down-converts the N-channel first excitation signal into N-channel signals with a frequency of f IF The intermediate frequency excitation signal; 5.

2. The digital acquisition processor (71) converts the N intermediate frequency pulse signals into a first digital baseband signal based on the reference clock to obtain a phase monitoring result of the intermediate frequency pulse signal; or, the digital acquisition processor (71) converts the N intermediate frequency excitation signals into a second digital baseband signal based on the reference clock to obtain a phase monitoring result of the intermediate frequency excitation signal.
