Simplified Doppler Frequency Shift Measurement Enabled by Serrodyne Optical Frequency Translation
IEEE Microwave and Wireless Components Letters（2022）
摘要
A simplified Doppler frequency shift (DFS) measurement approach based on Serrodyne optical frequency translation is reported. A sawtooth wave with high amplitude is sent to one phase modulation arm of a Mach–Zehnder modulator in conjunction with the transmitted signal to implement the Serrodyne optical frequency translation, as well as the optical phase modulation of the transmitted signal on the ...
