This article put forwards a simple microwave photonics measurement method for microwave doppler frequency shift (DFS) and angle of arrival (AOA). which obtains the information conveniently and precisely by comparing the frequency and phase shift between two channels signals. The DFS direction can be judged more intuitively thanks to the introduction of the reference signal. The system... https://www.nacrack.com/amazing-offer-Grand-Love-Reposado-Tequila-Red-Glass-Heart-save-extra/
