摘要：
A linear method for TDOA estimation of frequency-hopping signal is proposed in this paper, which can provide high-precision positioning for frequency hopping signal and fast TDOA estimation. First, according to the carrier frequency and the signal bandwidth in a frequency hopping cycle, the frequency hopping signal is filtered, and perform the Hilbert transform of a frequency hopping cycle, then the Hilbert transform results were to determine the phase difference. By a number of frequency hopping cycle phase sequence of linear equations, the corresponding solution determines the frequency hopping signal TDOA estimation. The analysis and simulations demonstrate the effectiveness of the proposed method, which can get more high precision of TDOA estimate with several frequency hopping cycles.
