For accurate localization of wideband signal stationary sources of known height, a novel algorithm is proposed using the information of time difference of arrival (TDOA) and frequency difference of arrival (FDOA) between two moving stations. This method uses the principle of synthetic aperture radar (SAR) imaging and the idea of direct localization for reference. The observing time is divided into fast time and slow time in sampling. TDOA is required in the fast time domain, and FDOA is estimated in the slow time domain. Cross correlation of frequency domain is operated first between the sampling signals of two stations, and range cell migration of signals is then eliminated by reference function and general Keystone transform. The joint TDOA and FDOA are finally estimated by applying 2-D Fourier transform and mapping the position of sources. The results of simulation show that the precision of location is close to Cramer-Rao low bound (CRLB) when SNR is high, and the proposed method can be still used for location in low SNR. Besides, with low computational cost, the proposed algorithm is especially applicable for observing unresolved multiple target localization with properties of high precision and super resolution.
