The Application Analysis in the Passive External Illuminator Radar Based on Extraction of OTH′s External Illuminator Signal
Currently external illuminator radar use chiefly direct-arrival-wave received.The SNR of direct-arrival-wave extracted by this mode is large.It is profitable to detection and process of target signal,but It is necessary that the receiving station and trans-mitting station are visual in-the-horizontal and the receiving antenna of direct-arrival-wave installed highly is required,this struc-ture application is large limited.Because of it,the idea that the signal by receiving illuminator signal in-the-horizontal in the height above sea level along sea zone become standard signal of external illuminator detective is proposed,and the detective mechaniza-tion、theory error model is analyzed,and combine actual engineering,realizable engineering sample machine is provided,property quota is analyzed,simulation fruit is provided,result indicate that the structure may apply subsequent projects.
