Research on a Passive Location Method Based on Single Target Detection

Due to the complexity of the battlefield environment, In many workplaces, Passive localization can locate the target position without emitting strong signals. A binocular ranging method suitable for small mobile aerial platforms has been studied and designed for this purpose. This method establishes spatial geometric relationships based on the elevation and azimuth angles of binocular observation targets, Analyze geometric relationships and locate target locations, But when the target is far away, The observation platform will be approximated as a monocular observation, At this point, the observation platform contract collaboration can be added for positioning. Using the least squares method for trajectory fitting of the positioning results, The overlimit is removed with the fitting curve, This article conducts positioning experiments on stationary and moving targets, respectively, The actual measurement results show that this method has high positioning accuracy and can meet practical application requirements.
