Accurate High-speed Frequency Meter for Doppler Initial Velocity Measurement
Accurate High-speed Frequency Meter for Doppler Initial Velocity Measurement is a scholarly work, published in 2018 in ''Problems of advanced micro- and nanoelectronic systems development''. The main subjects of the publication include acoustics, Doppler effect, electronic engineering, SIGNAL, metre, Multidimensional systems, measurement error, and computer science. The article considers the issue of high-speed frequency measurement of low-frequency signal for initial velocity estimation in Doppler velocity meter.Authors reviewed existing frequency measurement techniques and proposed another measurement method with a structure of the hardware frequency meter block for a system on FPGA controlling Doppler meter.The article gives a measurement error calculation for proposed method and analysis of developed structure characteristics on real signal.
