Radar Location Optimization based on ISAR Imaging

Inverse synthetic aperture radar (ISAR) can be used for high-resolution imaging of air targets and ship targets on the sea. At present, it has been widely used in military and civil, and plays its great advantages. As an important part of radar imaging technology, the ISAR is applied to the Yangtze River Bridge to monitor the ship targets in the bridge area, which can be used as the key basis for the safe operation of the Yangtze River Bridge. This paper uses FEKO software to model the Yangtze River Bridge and ships, introduces RCS and equivalent source to simulate and analyze the bridge body and piers of the Yangtze River Bridge, explores the influence of radar signal occlusion on the navigation of ships in the bridge area, and obtains the approximate radar blind area near the bridge area. The index suitable for ISAR image evaluation is selected, the index weight is determined by entropy method, and the comprehensive evaluation is obtained by weighted summation to optimize the location of radar station.
