Research of the aeroplane intelligent localization methods based on Synthetic Aperture Radar imagery

Synthetic aperture radar (SAR) presents prominent advantages, such as working in all-time and all weather condition, which makes it locate the aeroplane more advantageous. First, the article discusses the effect on aircraft location caused by factors such as topographic relief while SAR imaging. Then, proposes a method that calculates the areoplane´s spatial position based on the multi-angular cone model after images matching are finished between different SAR images. The experiments verify the high-precision location of aircraft with more than 4 matching points provided, which spells itself the fitting tool in positioning aircraft with scarce image matching points.
