Tracking and guidance system with modulated missile-mounted laser beacon

摘要: An improved tracking and guidance system is provided for line-of sight commanded missiles. The includes a missile mounted laser beacon which modulated at predetermined frequency. infrared sensor on unit receives the incoming optical energy provides corresponding electrical output. output signals are filtered to eliminate clutter those outside range of frequencies within modulated. then peak detected determine azimuth elevation window. Azimuth error detector circuits compare generate signals. utilized by provide updated commands.
