    Abstract: An error detector apparatus (42) producing a signal used in the computation of a missile guidance signal in an aircraft-based missile guidance and tracking system. The error detector apparatus (42) incorporates means (146), (148), (150), (152), and (154) for producing a first envelope signal from a tracking signal emitted by a missile. The envelope signal is then converted, along with a reference signal, to a digital signal by an analog to digital converter (158). A microcontroller (168) calculates an error correction signal from the digital signals. A digital to analog converter (160) converts the digital error correction signal to an analog error correction signal and outputs the analog error correction signal to the system for use in computing a missile guidance signal.

    Abstract: A coordinate transformation apparatus (138) in an aircraft-based missile guidance and tracking system for adjusting aircraft and missile position signals for a roll angle about the line of sight in the guidance and tracking system sight unit (40) caused by roll of the aircraft subsequent to firing of the missile. The apparatus (138) incorporates analog to digital converter means (140), (144), (156), (160) and (180) to convert the analog aircraft and missile position signals to digital signals for input into a microprocessor (168). The microprocessor (168) computes the roll angle as well as a change in roll angle over time around the line of sight of the sight unit (40) and subsequently adjusts the digital signals to compensate for the computed roll angle and change in roll angle. Digital to analog converter means (182), (186) and (190) convert adjusted digital signals to analog signals and output the adjusted analog signals for computation of missile guidance signals by the system.

    Abstract: A closed-loop missile tracking system (10) employs a missile (12) with a thermal beacon (22) and an optical beacon (24). A target designator (40) defines a boresight from a missile firing location, such as an aircraft, to a target. The closed-loop missile tracking system (10) employs a first tracker (48) and a second tracker (64) with a forward looking infrared (FLIR) sensor (52) to track the displacement of the optical beacon (22) and thermal beacon (24) from the boresight. The first tracker (48) generates a first set of azimuth and elevation error signals. The second tracker (64) further includes a video demultiplexing interface (70) which transforms serial multiplexed video signals, which are output by the FLIR sensor (52) and contain a field with M rows and L columns of pixels, into a demultiplexed parallel video signal. A video thermal tracker (VTT) (58) selects the N adjacent horizontal rows of pixels and generates a second set of azimuth and elevation error signals therefrom. The VTT (58) selects at least one of the first set of error signals, the second set or a combination thereof to guide the missile (12).

A target designator (40) defines a boresight from a missile firing location, such as an aircraft, to a target. The closed-loop tracking system (10) employs a forward looking infrared (FLIR) sensor (52) to track the displacement of the thermal beacon (24) from the boresight and generates a correction signal related to such displacement. The video demultiplexing interface (70) transforms serial multiplexed video signals, which are output by the FLIR sensor (52) and contain a field with M rows and L columns of pixels, into a demultiplexed parallel video signal containing N selectable adjacent horizontal rows of pixels (where N is less than M). A video thermal tracker (58) selects the N adjacent horizontal rows of pixels and generates azimuth and elevation error signals which are transmitted to the missile (12). The trajectory of the missile (12) is continuously corrected to align the thermal beacon (24) with the boresight.
