A Method of Complicated Motion Ship Imaging

In order to protect our country's territorial waters from infringement and maintain maritime rights and interests, it is necessary to establish a marine defense system that combines both offshore defense and far sea defense. Coast-to-shore/GEO satellite-ship-to-ship bistatic inverse synthetic aperture radar (inverse synthetic aperture radar, ISAR) has all-day and all-weather characteristics, and can realize long-distance continuous tracking, imaging and identification of ship targets in offshore/far sea areas. In addition, these two bistatic ISAR imaging systems also have the advantages of high concealment, strong anti-strike capability, high flexibility, multiple imaging modes, and rich target information, thus improving the reliability of the marine defense system.
