An MKV interceptor includes a carrier vehicle (CV) that supports the deployment of M kill vehicles (KVs) and provides centralized acquisition and discrimination pre-ejection. Pre-ejection each KV acquires and transmits IR imagery, and possibly visible imagery, via an internal communication bus to a central processor on the CV. The central processor spatially registers the IR images from the different KVs, either directly from the IR images themselves or using the visible imagery, and sums the IR (and visible) images to form a registered spatially averaged IR image. This image has the same resolution but higher SNR than any one of the KV IR images. The central processor uses this registered spatially averaged image during pre-ejection acquisition and discrimination modes. The key benefit is the elimination of independent CV 'sense capability', which is large, heavy and expensive, and was required by either the 'command guided' or 'sharing' concepts.

Multiple kill vehicle (MKV) interceptor with improved pre-ejection acquisition and discrimination

A hyper-velocity impact sensor including an optical fiber probe that transmits an optical pulse generated during impact with an object, a spectroscopic analyzer that receives the optical pulse and produces spectral information about the optical pulse, a connecting optical fiber configured to convey the optical pulse between the optical fiber probe and the spectroscopic analyzer, and at least one processor coupled to the spectroscopic analyzer and configured to receive and analyze the spectral information to determine at least one chemical element or compound contained in the object.

Hyper-velocity penetrating probe for spectral characterization

A hyper-velocity impact sensor is configured to probe a mass of material consumed upon impact with an object. The probe can extract density and thickness characteristics of the impacted object, which can be used to classify the object.

Hyper-velocity impact sensor

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.

Long range KV-to-KV communications to inform target selection of follower KVS

By sharing tasks between the CV and the KVs, the MKV interceptor provides a cost-effective missile defense system capable of intercepting and killing multiple targets. The placement of the acquisition and discrimination sensor and control sensor on the CV to provide target acquisition and discrimination and mid-course guidance for all the KVs avoids the weight and complexity issues associated with trying to 'miniaturize' unitary interceptors. The placement of either a short-band imaging sensor and headlamp or a MWIR sensor on each KV overcomes the latency, resolution and bandwidth problems associated with command guidance systems and allows each KV to precisely select a desirable aimpoint and maintain track on that aimpoint to impact. An implicit divert and attitude control system (DACS) using tow or more divert thrusters performs KV divert and attitude maneuvers to respond to the command guidance pre-handover and to maintain track on the aimpoint to terminal intercept post-handover.
