HARMONIC SHUTTERED SEEKER |
摘要 |
A dual-mode, semi-active, laser-based and passive image-based seeker for projectiles, missiles, and other ordnance that persecute targets by detecting and tracking energy scattered from targets. The disclosed embodiments use a single digital imager having a single focal plane array sensor to sense data in both the image-based and laser-based modes of operation. A shuttering technique allows the relatively low frame-rate of the digital imager to detect, decode and localize in the imager's field-of-view a known pulse repetition frequency (PRF) from a known designator in the presence of ambient light and other confusing target designators, each having a different PRF. |

1. A method of detecting and decoding locking pulses having a predetermined PRF, the steps comprising:
dividing a pulse interval of the predetermined PRF into a plurality of repeating subintervals; shuttering alternating ones of said plurality of repeating subintervals with an exposure; determining whether two or more received pulses are received in one of said subintervals by said shuttering step; and identifying said one of said subintervals of said pulse interval, thereby detecting and decoding said received pulses of said one of said subintervals as having the predetermined PRF. |
