SI Xi-cai · Journal of Projectiles.Rockets.Missiles and Guidance · 2006
Aiming at the characteristic of LFM radar signal,this paper analyzes the thoery of distilling instant frequency of LFM signal based on the means of instant phase firstly.Secondly,this paper resumes phasic sequence by confirming illegible value and actualizes distilling instant frequency.By theory analyzing and simulating,it is shown that this method's merit is little calculation and good real-time.
