ISAR, or Inverse Synthetic Aperture Radar, is a type of radar technology used primarily for imaging moving targets. It works by emitting radar waves and analyzing the reflected signals to create detailed images of objects, such as vehicles or aircraft, in motion. This technology is particularly useful in military and surveillance applications. ISAR differs from traditional synthetic aperture radar (SAR) by focusing on moving objects rather than stationary ones. It can provide high-resolution images even in challenging conditions, making it valuable for various fields, including defense, aviation, and maritime surveillance.
