An Algorithm of Digital Frequency Discrimination Based on Distributed Arithmetic
Zhou Zhi-yin · Modern Radar · 2007
Aiming at the disadvantages of analog frequency estimation in traditional receiver,this article proposes an algorithm of digital frequency discrimination based on distributed arithmetic.Compared with other similar methods,this algorithm doesn′t need phase estimation.It estimates signal Doppler frequency shift directly by first-order differential structure.This technique may be easily implemented in programmable digital device,and calculate can target-radar radial velocity.
