A New Method to Estimate Signal Number by Echo’s Phase

ZHANG Yi, KE Heng\|yu, WEN Bi\|yang, WU Xiong\|bin (School of Electronic Information, Wuhan Univercity, Wuhan 430072, Hubei, China)  
Due to the failure of tradional determination method of signal number,when using harmonic retrieval to detect target in frequency domain by HF ground wave radar,a new method to estimate the number of signal by echo’s phase is developed in this paper.The theory based on is presented,the processing procedure and results of real data are investigated at last.
