摘要： An EO sensor is configured to time multiplex a primary optical channel that provides high detection sensitivity to maintain high SNR and a multi-filtered optical channel that provides detection in different measurement bands (e.g. spectral, polarization, amplitude or phase). The channels may, for example, be time multiplexed based on range to target or within each integration period of the EO sensor. The multi-filtered optical channel uses a field directing array to sample the FOV to form different optical sub-channels that are filtered by different optical filters. These sub-channels may be spatially multiplexed onto different sub-regions of the detector or may be time multiplexed onto the entire detector. The light modulator used to time multiplex the primary and multi-filtered optical channels may be used to time de-multiplex spatially overlapping regions of the FOV onto a pixel of the detector in order to detect high spatial resolution images with low resolution detectors.

摘要： A KV-based missile defense system and method of strategic engagement provides performance improvement for both singleton and raid scenarios by launching multiple interceptors that place a follower KV in a trailing position with respect to a lead KV. Knowledge of the target cloud gained by the lead KV is transmitted to the follower KV and incorporated to inform the target selection of the follower KV. The follower KV trails the lead KV with sufficient spacing in time and distance to select a target and maneuver to engage the target pre-acquisition. This also allows the follower KV to receive and incorporate knowledge of target impact by the lead KV. This knowledge may be transmitted back to another follower KV and so forth in a “string” of KVs to inform target selection and down to the ground to inform strategic engagement. Updated non-KV observational data can be uplinked and transmitted forward along the string to the lead KV.

摘要： A digitally scanned multi-cell EO sensor comprises a low-resolution multi-cell imaging detector. An array of optical focusing elements decomposes the sensor's FOV into at least four sub-fields. A sub-field directing array and focusing optic direct the optical radiation onto the imaging detector. In a first tilt mode, the optical radiation from the sub-fields is directed into at least four spatially separated sub-regions that each map to a different detector cell. A high-resolution spatial light modulator (SLM) digitally scans the FOV to select different portions of the FOV to map onto the different detector cells to time demultiplex spatially overlapping portions of the FOV onto each detector cell to stitch together a sub-image of a selected area of the FOV up to the native resolution of the SLM.
