Guided missile dual mode seek head

摘要

A dual-mode seek head for a guided missile has a four-quadrant detector 12 for target acquisition by means of the laser pulses reflected by the marked target Z, and an imaging IR bolometer 16 receiving the IR radiation emitted by the target Z. The laser and IR radiation is received through a common entry window and delivered to the respective sensors. After the target marking has been carried out, signal-processing electronics 20 process exclusively the signals delivered by the IR bolometer 16 for guidance signal generation for the purpose of generating the guidance signals for the final approach phase of the guided missile. This two-stage approach enables the use of much simpler IR sensors.
