Target Detection Method Based on Accurate Prediction of Environment

In order to explore how to construct an inversion system based on the characteristics of the target when the target has a disturbance to the background electromagnetic, the target characteristics are inverted. In this paper, a target detection method based on detecting electromagnetic disturbances in steady-state space is proposed, a target detection method based on Babinet and Fresnel zone theory is proposed, and a weak electromagnetic disturbance signal enhancement method based on differential cancellation is used to enhance the upper-air signal fluctuation. The space electromagnetic field disturbance based on the Beidou satellite signal as the external radiation source is simulated and analyzed, and the target is judged to appear and locate the target according to the fluctuation received by the ground station.
