摘要
Forward scatter radar can achieve target detection by capturing the signal disturbance caused by the target's crossing of the baseline. It has certain potential in stealth aircraft's target detection. The study of target crossing characteristics is of great significance to signal detection and parameter estimation. Firstly, the forward scatter radar net model based on global navigation satellite system (GNSS) is constructed. The conditions and range of forward scattering observation are analyzed. Then, time and frequency domain statistical characteristics are proposed to describe the signal characteristics of the target's crossing the baseline based on the forward scattering dynamic signal model. Finally, the influence of target crossing position and motion parameters on the scattering signal and its statistical characteristics is analyzed through simulations. The variation law of the forward scattering signal characteristics is revealed, which provides the reference value for subsequent improvement of detection probability of crossing events and parameter estimation accuracy. © 2024 Chinese Institute of Electronics.
