Abstract: A generalized Hough transform is used to acquire and track vehicular targets for missile guidance. This is accomplished by recognizing that most vehicles have silhouettes that may be described as a “rounded rectangle”. The position and shape of such rounded rectangles is described in terms of 5 parameters (xc, yc, a, b, θ) where xc, yc are the center coordinates, a,b are the major and minor axis and Θ is the orientation. The computation of a five dimensional Hough transform on an image including such a target will produce the five parameters that provide the “best fit” rounded rectangle to the target. These parameters are then passed to a missile tracker. This capability can be used to improve track gate handoff from the automatic target recognizer (ATR) to the missile tracker, changing aspect ratios of maneuvering targets, limited lock-on after launch (LOAL), aimpoint designation and fire control system to missile seeker handover.

Abstract: A single dual mode monolithic focal plane array having an active sensor and a passive sensing capability is switched from one mode to the other by switching the bias across the cells of the array from a passive IR mode to an active LADAR mode, with the monolithic dual mode focal plane array having applications in missile target seekers and laser target designators. The switching is accomplished by increasing the gain of the array by as much as 30 times that associated with IR detection when laser return pulses are expected. Thus, there need be no mechanical changes to the array to afford both passive IR sensing and an active LADAR pulse detector. Nor need there be two different focal plane arrays, one for IR and one for laser radiation, which leads to boresighted alignment problems.

Abstract: A method for guiding a missile to a target. The method includes the step of providing a surface-based radar system having an electronically beam steerable antenna system adapted for continuous mechanical rotation about an axis. During a pre-terminal, semi-active missile homing guidance phase, the beam produced by the antenna system is electronically rotated by the antenna system in a direction counter to the direction of the mechanical rotation of the antenna system to thereby increase radar system illumination time on the target. Further, during the increased illumination time, the beamwidth of the surface-based radar system beam is increased. During, a subsequent terminal, active homing missile guidance phase, guiding the missile to the target with the pre-terminal, semi-active missile homing guidance phase using the surface-based radar system and establishing an angular orientation for a missile-borne antenna system at the commencement of the terminal, active missile homing guidance system phase.

Abstract: A dual mode target seeking system for airborne vehicles which operates under two different frequencies simultaneously includes a radio frequency antenna comprising a slotted plate defining a ground plane with an image plate positioned in front of the ground plane at a distance chosen such that multiple reflected rays are in phase with each other and with waves incident on the image plate. The slotted plate and image plate have aligned central openings through which an electro-optical system for operating under a chosen electro-optical frequency range, for example under infrared frequencies, projects. The electro-optical system includes a detector unit positioned behind the antenna and a focussing system for directing incoming electro-optical radiation into the detector unit. The focussing system includes first and second lenses mounted in the openings in the image plate and slotted plate, respectively. The lenses each transmit radiation in the chosen electro-optical frequency range while at least partially reflecting radio frequency radiation.

Abstract: An active (laser) and passive guidance system having a common sensor (siln-vidicon) for target acquisition, non-imaging seeker (four quadrant detector integrated with four single detectors, gyro optics, electronics), and aim-point correlator. In the passive mode, the pilot detects the target on the sensor's visual display; aligns the seeker with the target by aim-point correlation, and initiates seeker tracking. In the laser mode, the seeker acquires and tracks the target, the acquisition sensor scans the area, and its signals are correlated with the seeker four detector signals. The point of maximum correlation is indicated on the display of the acquisition seeker and shows the point of laser illumination and seeker tracking.
