An improved system is provided for aiming a shotgun-based or other countermeasure system so as to be able to countermeasure incoming rockets or projectiles. In one embodiment a shotgun aimed and controlled by the subject system projects a pattern of pellets to intercept a rocket-propelled grenade or incoming projectile. The fire control system uses a CW two-tone monopulse radar to derive range and angle of arrival within 150 milliseconds, with range and angle of arrival measurements having approximately twice the accuracy of prior CW two-tone monopulse radars. The improvement derives from using all of the information in the returned radar beams and is the result of the recognition that one can use the Sum and Difference signals to assemble a two-by-two Rank One matrix that permits using singular value decomposition techniques to generate range and angle of arrival matrices in which all available information is used and in which noise is eliminated.

A fire control system for a boost phase threat missile includes sensors for generating target-missile representative signals, and a multi-hypothesis track filter, which estimates the states of various target hypotheses.

A fire control system that includes an array of photodiode elements. For each element of the photodiode array, there is a specific optical path in the atmosphere leading from the laser to a target and back from the target to the element. Accordingly, each element of the detector array can be regarded as if illuminated by a distinct light source. For short time periods (in the range of tens to hundreds of milliseconds) the shape or spatial distribution of the refractive-index irregularities does not significantly change, and the irregularities drift with the atmospheric wind. By measuring the signal fluctuations by any element of the photodiode array, it is possible to compute the crosswind velocity. By comparing signal fluctuations patterns of two or more elements it is possible to define the wind direction and to determine the turbulence strength value.

In a fire control system for an elevator, the time for the fire and smoke to reach the elevator hall of each floor of a building during fire is pre-calculated as the evacuation time of the floor. When the evacuation time of a floor is longer than the time for making a car respond to a rescue call from the evacuation floor, the floor is judged as a rescue floor, and when shorter, the floor is judged as a non-rescue floor. Furthermore, the order in which the rescue is carried out among the rescue floors is determined. Accordingly, it is possible to rescue remainders on a rescue floor using an elevator as an evacuation means. Moreover, since rescue operation by the elevator is performed with the order of rescue determined, rescue operation suitable for the conditions of the fire can be realized.

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.
