Abstract

The location of three-dimensional coordinates of the target is a very important research in the fields of radar, electronic countermeasures and wireless communication. It plays an extremely important role in the drawing of topographic maps, environmental monitoring, disaster prevention and modern warfare. At present, there are problems that the location method is complex and the location accuracy is not high. Aiming at this, this paper proposes a method to locate the strong scattering point by using SAR image, which is combined with the range Doppler model to locate the target. Analytical solutions are derived from the theory of equations and the error factors are analyzed and discussed. Finally, an experiment was carried out to locate the five corner reflector targets with strong scattering characteristics using synthetic aperture radar, and the three-dimensional coordinates of the strong scattering point targets were obtained. The experimental results demonstrate the reliability of the method.
