A Novel Phase Error Calibration Method for Interferometer System
The influence of electromagnetic environment,front-end components and array element coupling,etc.on the phase error of the interferometer system are analyzed,and a novel phase error calibration method for interferometer system is proposed.The phase correction of full-band radar signal is performed through self-test,and the confidence evaluation criterion is used to determine the measured results.The actual measurement results indicate that this method can calibrate the system errors quickly and accurately,improve the direction finding accuracy of the system greatly,provide important technical means for the realization of system function,and has certain engineer-ing application value.
