Scatterider guidance system for a flying object based on maintenance of minimum distance between the designating laser beam and the longitudinal axis of the flying object

Abstract: The scatterider guidance system is mounted on the flying object that is toe guided toward a more direct impact on the selected target. The system utilizes a designating beam of laser pulses that is emitted from the launch pad toward the target and atmospheric particles that scatter the laser pulses to calculate the guidance commands that lead the flying object to follow the laser beam closely. Upon detection by the scatterider sensors of the laser light that is scattered by the atmospheric particles, the perpendicular radial distance between the laser beam and the longitudinal axis of the object in flight is calculated by the onboard guidance electronics and subsequently used to generate the deflection commands. The deflection commands, in turn, are used to deflect aerodynamic control surfaces of the object such that the object approaches and stays close to the laser beam. This guidance system is activated as soon after launch as possible and continues until the object impacts on the target.

Dynamic route guidance method oriented to urban traffic

Abstract: The invention discloses a dynamic route guidance method oriented to urban traffic, relating to various optimal route planning methods in a geographic information system (GIS) and an intelligent traffic system The method comprises the following steps: through taking a GIS (geographic information system) software product ArcGIS road model provided by the Environmental System Research Institute (ESRI) in America as the basis, loading a road traffic map of the Beijing city, simulating the operation efficiency of twelve route planning methods such as a PSP (play station portable), Dijkstra and soon in different road traffic conditions, and displaying the dynamic traffic information of major roads in real time to realize the presentation of the dynamic traffic flow information; and simulatingthe operation efficiency of different route planning methods in dynamic traffic condition by successfully applying the dynamic traffic flow information in the computation of the dynamic optimal route The prototype system belongs to the field of transportation, and can be applied to the simulation experiment of the optimal route planning method in an intelligent transportation system, a vehicle navigation system and the GIS, thereby providing a reference and basis for the research on road guidance systems

Self defense missile

Abstract: A self defense missile, for bombers in particular, wherein the slower flying bomber is being overtaken by a faster flying hostile aircraft in the rear quadrant. The self defense missile is an unpowered missile having wings to provide lift, a guidance system to control the direction of flight of the missile, and a homing detection in the tail of the missile to cause the missile to fly into the path of the hostile aircraft. In operation, the self defense missile is launched parallel to the direction of flight of the bomber. As the missile slows down, the wings give it lift to keep it at the appropriate altitude. The homing detector in the tail guides on the approaching hostile aircraft and the guidance system keeps the self defense missile on a collision course. This action by the self defense missile and the increasing speed of closing caused by the slowing of the missile, forces the hostile aircraft to break off pursuit to take evasive action of face destruction upon intercept when the self defense missile is overtaken.
