DOA Measurement of Moving Targets

摘要

This paper mainly introduces the moving target detection experiments using a K-Band radar system. Phase comparison monopulse technology is used to measure target direction-of-arrival (DOA) for both the Doppler mode and linear frequency modulated continuous wave (FMCW) mode. For the Doppler mode, a Fourier fitting of the Doppler signal is carried out for the calculation of phase difference. For the FMCW mode, a tolerance factor is proposed to reduce the target DOA error. The average DOA error is less than 1°.
