    Abstract
  • Passive localization methods based on synthetic aperture imaging offer high positioning accuracy. However, in scenarios involving multiple radar emitters transmitting Linear Frequency-Modulated (LFM) signals, distinguishing signals that are overlapped in the time and frequency domains can be challenging. This phenomenon, known as phase overlap, results in a significant degradation of localization performance. To address this issue, the present paper proposes a single-satellite multi-radar-emitter passive localization method based on synthetic aperture imaging using time-frequency parameter estimation. First, a signal model for multiple radar emitters transmitting LFM signals is constructed. The time-frequency parameters of the multiple radar emitter signals are estimated concurrently via a combination of Short-Time Fourier Transform (STFT) and DBSCAN. A rapid approximation of the azimuth chirp rate is attained through a coarse-to-fine search strategy founded upon the use of the STFT. The accurate localization of multiple radar emitters is ultimately realized through the implementation of two-dimensional focusing in the range and azimuth dimensions. The Cramer-Rao lower bound of the proposed method is derived on this basis. The experimental findings demonstrate that the proposed method enhances the localization accuracy by approximately 10 km at a signal-to-noise ratio of −10 dB, in comparison with the enhanced real-valued space-time subspace data fusion-based direct positioning method. Moreover, it reduces the computational time by half relative to the CLEAN-based synthetic aperture multi-source localization approach.
