A radar ranging algorithm based on characteristic decomposition power spectrum estimation

Abstract

The linear frequency modulation (LFM) signal is the main signal form of the high resolution radar. By analysis for the principle of the LFM radar signal to realize the high range resolution profile and the impact of clutter and noise over target echo signal, we proposes the method of using spectrum estimation based on the characteristic decomposition to estimate the frequency and realize the LFM signal range profile. The simulation results prove that this method to the goal 1-D range profile is effective under low signal-to-noise ratio conditions.
