Theoretical Analysis on Blind Detection Method of Shortwave Communication Electronic Signal Based on Wireless Network

Radio communication is an important means of ensuring operations and command on the modern battlefield. Especially when commanding moving targets, it is even the only means of communication. This paper focuses on the problem of blind detection and parameter blind estimation of shortwave frequency hopping signals based on array signal processing, that is, in the absence of sufficient prior information, fully excavate the time domain, frequency domain and spatial characteristics of the signal, and combine the shortwave FH signal In this paper, a method for implementing blind detection and parameter blind estimation of shortwave signals based on broadband processing is proposed. The results show that the method improves the blind inspection efficiency by 7.2%.
