Abstract：To addressthe issue of communication quality degradation caused by phase misalignment in multi-chanel signals withincomplex electromagnetic environments，areal-timecalibration method forKu-bandultra-narrowbandsignals basedonradio frequencysystem-on-chipis proposed.Thesystemadopts aconfigurable radio frequency front-endand digital compensation colaborativearchitecture，combined withtime-frequency domain hybridcorrection algorithm，and adopts a multi-channel parallel processng hardware structure to achieve synchronous processingand phase compensationof multichannelsignals，breaking through theaccuracyand real-time limitations of taditional phasedetection methods in processing narowband signals.Theexperimental resultsshow that the system can effectively improve phase consistency in strong interference environments.After calibration，the phase error is controlled at ±0.02∘ ，which is 80% higherthan theminimum error of ±0.1∘ in the vector network analyzer calibration scheme.The signal quality after calibration mets the rquirements of tactical systems.
