|
 | A signal processing circuit for producing a warhead firing pulse when the warhead is in a position to cause maximum target damage in a missile, target encounter. The received doppler signal is processed through filter circuits and a first band-pass amplifier. A second bandpass amplifier tuned to pass a narrow portion of the frequency spectrum above the doppler signal is connected in parallel with the first amplifier and its output ... |

|
| A system for testing the performance and vulnerability of proximity fuzes under simulated live hardware conditions. The performance of the system is evaluated by the application of a repeater jammer signal within the cutoff range of the proximity fuze which is mounted in a free space test site. Beyond the cutoff range, the vulnerability of the proximity fuze is tested by the application of an unlimited number of modulated interference ... |

|
| The patent describes a two channel optical fuzing system for determining that a true target is present by initiating a gating pulse when the forward looking channel first detects what appears to be a target and initiating an arming signal when the rearward looking channel sees the same target. If the arming signal initiated during the time interval of the gate pulse, a decision circuit passes an output pulse to ... |

|
| The patent relates to a fuzing system in which a third or obscuration channel having a forward looking narrow beam width detects a target and generates a signal which is fed to a sequence computer. If within a predetermined time after receipt of the third channel pulse, a second pulse is received from either of the two regular infrared channels, a pulse is generated to actuate the firing circuit. If ... |
