Comparative Analysis of Single-View and Multi-View Airborne SAR Positioning Error and Course Planning for Multi-View Airborne SAR Optimal Positioning

Airborne synthetic aperture radar (Airborne SAR) can accurately locate key targets and regions by using the flight parameters of aircraft relative position information between target which be obtained from airborne positioning orientation system (POS). In course flight, will deviate ideal path due to atmospheric turbulence, results in calculation deviating actual position. order improve accuracy, it is necessary study influence motion error on error. This discusses accuracy single-view SAR perspective linear Range-Doppler algorithm (RDA), deduces multi-view transfer model based model. Based these, we analyze main factors that affect two methods detail quantitatively reveal mechanism method compared with method; also solve problem planning for optimal positioning. The research provide theoretical support analysis influencing correction SAR.
