Abstract

A photonic-assisted transceiver for microwave Doppler frequency shift (DFS) measurement, which possesses capabilities of generating a frequency-quadruplicated transmitted signal and evaluating the speed and the orientation of the moving object, is proposed and demonstrated by simulating. In the transmitter, the frequency-quadruplicated transmitted signal is obtained by beating the carrier-suppressed ±2nd sidebands. In the receiver, a low-frequency reference signal is introduced to estimate the sign of the DFS. Different from the other DFS measurement solutions based on microwave photonics, the proposed approach takes the advantages of generating a high transmitted signal, employing a low reference signal, and having no use of an optical filter.
