A terrestrial acoustic sensor array for detecting and preventing airspace collision with an unmanned aerial vehicle (UAV) includes a plurality of ground-based acoustic sensor installations, each of the acoustic sensor installations including a sub-array of microphones. The terrestrial acoustic sensor array may further include a processor for detecting an aircraft based on sensor data collected from the microphones of at least one of the plurality of acoustic sensor installations and a network link for transmitting a signal based on the detection of the aircraft to a control system of the UAV.

A launchable, multi-sensory distraction grenade including a base, three outer grenade walls arranged together on the base to pivotally move from a first position, to a second position, extending outward laterally from the base in different directions, to form lateral legs to support the base after it lands on a surface, a plurality of spring fingers retaining the walls in contact with the base, at least two distraction devices mounted in the grenade for initiating an extended period of personnel distraction in the area of the grenade with its walls in their second position, a distraction device ignitor and safety trigger at least a portion of which is external the casing for controlling the ignition means.

An apparatus for achieving remote guarding of an area with adjustable effect on unauthorized entrants, comprising an operator station including a signal receiver with television display, radiant energy selection control, and energy level controller, a first sensor means placed about the area for detecting the presence and movements of entrants to the area, the visual effects of later radiation directed toward them, and generating signals in response thereto, a source of radiant energy including at least one transmitter of the energy for broadcasting the energy into the area, upon selection of the type of radiant energy from the selection control, and of a level controlled by the energy level controller, the radiant energy of a nature and intensity capable of varying in strength and duration as to cause different observable effects on intruders present in the area who do not leave the area upon command, second sensor means placed about the area for detecting the onset of and intensity of the radiant energy broadcast into the area and generating signals in response thereto, first transfer means for transferring the generated signals from the first sensor means and separately transferring the generated signals from the second sensor means to the signal receiver in the operator station to allow the operator real-time observation of the area. and second transfer means for transferring control signals from the operator station to the radiant energy source and transmitter to vary the type and intensity of the radiant energy broadcast into the area to prevent further intrusion into the area.

An apparatus and method for simulating atmospheric scintillation includes a scintillation disk and a motor for rotating the disk at a substantially high speed. The disk has a dense varied pattern of substantially small closely spaced holes. The holes have different sizes and are arranged with a spatial distribution that is gaussian in amplitude and poisson distributed in separation. The motor can spin the disk to produce desired temporal variations as energy from the energy source passes through the holes of the disk.

A roll measurement system for a flight vehicle, such as a tank-launched ged projectile or guided missile, includes a power source and a pulsed laser, such as a laser diode, which propagates a laser beam which is focused into a narrow conical beam and directed toward the earth. The laser beam's reflections from the earth are detected, for example, by a photo-diode, and converted into an analog electrical signal. The signal is converted to digital form and analyzed to determine its nadir (the shortest path-length to the earth). A microcomputer compares the immediate nadir determination with stored nadir determinations to compute the angle and rate of roll of the flight vehicle.

A guidance system for a beam rider missile, having a novel coded light beam projector at an aiming station, for use by a missile-mounted receiver. The projecting means contains a rotating transparent reticle through which the beam is transmitted, the reticle having an opaque radial portion in a curved 'leaf' shape. When the diameter of the projected beam is held constant at the missile distance during flight, the position of the missile in polar coordinate form is given by the relative angular position and duration of the blocked-out portion of the beam received at the missile.
