A method for allowing accurate navigation to a target regardless of GPS jamming levels. A method to update the navigation solution of an object being navigated toward a target based upon seeker measurements in at least one of three electromagnetic frequency domains: infrared, visible, and radio frequency (RF).

Navigating in GPS denied environments using a dedicated aerial vehicle

An apparatus and system for allowing accurate navigation to a target regardless of GPS jamming levels. An apparatus and system can be used to update the navigation solution based upon seeker measurements in at least one of three electromagnetic frequency domains: infrared, visible, and radio frequency (RF).

Method for navigating in GPS denied environments

A method of using a bistatic passive radar system for tracking a plurality of targets utilizing transmitted radar signals from at least one satellite platform in a geosynchronous orbit with the earth, a radar receiver capturing signals from a reflection of the transmitted radar signals from each target, tracking a position of each target over time, and a processing method for computation of a fire control solution of each target.

Method of using a microwave and millimeter frequency bistatic radar for tracking and fire control

The present invention provides an unpowered low-cost 'smart' micromunition unit for a weapon system for defense against an asymmetric attack upon ships and sea or land based facilities. A plurality of air dropped micromunition units are each capable of detecting and tracking a plurality of maneuvering targets and of establishing a fast acting local area wireless communication network among themselves to create a distributed database stored in each deployed micromunition unit for sharing target and micromunition unit data. Each micromunition unit autonomously applies stored algorithms to data from the distributed database to select a single target for intercept and to follow an intercept trajectory to the selected target. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of the claims.

Smart counter asymmetric threat micromunition with autonomous target selection and homing

A bistatic passive radar system for tracking at least one target utilizing means for transmitting radar signals from at least one satellite platform in a geosynchronous orbit with the earth, means for receiving radar signals from a reflection from each target, means for tracking a position of each target over time, and means for computation of a fire control solution of each target.

Microwave and millimeter frequency bistatic radar tracking and fire control system

A phased array balloon antenna having an inner membrane coupled to an outer membrane and a phased array antenna connected to an inner membrane. The phased array antenna transmits an energy towards a reflective film on the outer membrane, reflecting the energy outwards and illuminating an area smaller than that illuminated by the phased array alone.

Balloon antenna

A digitally formed monopulse radar employing dynamic real-time calibration uring operation. The invention has a transmitter section, timing circuit, RF section, IF section, in-phase and quadrature section and a digital signal processor. A portion of the transmit signal is diverted from the transmitter section for preparation of calibration factors during the calibration period between receive signals. The calibration factors prepared by the digital signal processor are applied by the processor to antenna received signals during the receive mode and to produce the corrected sum and delta pitch, and delta yaw signals and the tracking errors .epsilon..sub.y and .epsilon..sub.p.
