Direction Finding for Electronic Warfare Systems Using the Phase of the Cross Spectral Density
2002 (English)In: RadioVetenskap och Kommunikation (RVK), 2002, 264-268 p.Conference paper (Refereed)
In modern electronic warfare systems there is a need for direction-ﬁnding of transmitters using waveforms for military stealth communication. In this paper, a correlation-based method is investigated utilizing the phase of the cross spectral density to estimate the time-diﬀerence-of-arrival from a two-channel digital receiver. A least squares method is reviewed, and its performance is investigated by theoretical analysisand by Monte-Carlo simulations. Proper Cramér-Raobounds are derived. It is shown that the method is statistically eﬃcient for ﬂat spectrum signals. The method is found to be a promising method for use against military communication in an electronic warfare direction-ﬁnding system.
