    摘要: Upon loss of a valid track of a remotely-sensed command guided vehicle, a delta actuator command including an orthogonal component orthogonal to the straight-line path is generated as a next sample of a time-based alternating signal. The time-based delta actuator command is added to the nominal actuator command, which is “held” upon loss of valid track, to maneuver the vehicle in first and second orthogonal directions back and forth across the straight-line path to increase an area of vehicle motion relative to the tracker's FOV. This increases the likelihood of recapture of the vehicle given vehicle motion after track is broken. The penalty is a reduction in energy efficiency. In certain embodiments, this is accomplished without modification to guidance system hardware or the existing tracking valid or invalid guidance algorithms.

    摘要: Apparatus and associated methods relate to a dual-mode seeker for a guided missile equipped with seeker/designation handoff capabilities. The dual-mode seeker has Semi-Active Laser (SAL) and Image InfraRed (IIR) modes of operation. SAL-mode operation includes detecting laser pulses reflected by a target designated by a remote Laser Target Designator (LTD) and determining target direction using the detected laser pulses. SAL-mode operation also includes determining the Pulse Repetition Interval (PRI) of the detected laser pulses, and predicting timing of future pulses generated by the LTD. IIR-mode operation includes capturing Short-Wavelength InfraRed (SWIR) images of a scene containing the designated target and determining target location using one or more image features associated with the designated target. After the target direction can be determined using the IIR-mode of operation, an illuminator projects a signal onto the designated target so as to communicate to a remote operator that LTD target designation can be suspended.

    摘要: Apparatus and associated methods relate to a seeker for a Semi-Active Laser (SAL) guided missile. The seeker has a Short-Wave InfraRed (SWIR) camera and a Pulse Timing Logic (PTL) detector. The PTL detector has a SWIR photo detector axially aligned with a lens stack of the SWIR camera. The SWIR photo detector is configured to detect a sequence of SWIR pulses generated by a SAL target designator and reflected by a designated target. The PTL detector has a pulse timer configured to identify a sequence pattern of the detected sequence of SWIR pulses, and to predict a timing of a next SWIR pulse in the identified sequence pattern so as to synchronize exposure of the SWIR camera to capture a next image of the designated target at the predicted timing of the next SWIR pulse. Such exposure timing can advantageously improve the signal to noise ratio of the next image.

    摘要: A method to spread laser photon energy over separate pixels to improve the likelihood that the total sensing time of all the pixels together includes the laser pulse. The optical signal is spread over a number of pixels, N, on a converter array by means of various optical components. The N pixels are read out sequentially in time with each sub-interval short enough that the integration of background photons competing with the laser pulse is reduced. Likewise, the pixel read times may be staggered such that laser pulse energy will be detected by at least one pixel during the required pulse interval. The arrangement of the N pixels may be by converter array column, row, two dimensional array sub-window, or any combination of sub-windows depending on the optical path of the laser signal and the capability of the ROIC control.

    摘要: A beam rider guidance system is presented which uses a rotating laser light pattern to enable a weapon-borne laser receiver to derive its position relative to the beam axis. The guidance beam consists of changing light patterns detected and decoded by the receiver as a guidance code, which defines the unique weapon position in the beam. The code is composed of four distinguishable patterns of light bars which can be detected and decoded into electrical pulses by the laser receiver located anywhere within the confines by the guidance beam.
