Abstract: A fuzing system for non-spinning or substantially non-spinning weapons is implemented by means of wide angle optics providing at least forward-hemisphere coverage, an array of infrared detectors and a microprocessor for image and data processing, aim-point selection, directional-warhead aiming and skewed-cone fuzing. The skewed-cone fuzing has a generatrix which is the vector sum of missile velocity, warhead velocity and the negative of target velocity.

Abstract: A passive mine detection apparatus useful for searching out buried mines, exploits natural soil emissions at microwave frequencies and unique interference-induced spectral reflection signatures from planar surfaces of buried mines interacting with the soil emissions. The apparatus comprises a focussed beam antenna, low noise amplifiers for respective polarizations, baseband converter, spectrum analyzer, A to D converter, signature recognition processor, display and/or alarm. Hand-held and vehicle-mounted implementations are disclosed.

Abstract: To provide improved performance in a microwave antenna, particularly for use in a Doppler navigation system, rectangular arrays obtained from truncated slanted arrays are used to obtain beam shapes which exhibit a high degree of independence from over-water shifts.

Abstract: An attachment is provided for aircraft, and particularly for helicopters, for use in conjunction with a microwave interference pattern sensor (MIPS) system, to sense low velocities, for example, such as are encountered when the helicopter is in a hover mode. The attachment includes an antenna array which is separated from the MIPS antenna array, and which comprises two sets of transmitting and two pairs of receiving antenna horn apertures mounted in orthogonal relationship with one another, the transmitting apertures of each set being scanned in sequence to produce a moving energy pattern which is intercepted by the receiving antenna apertures of the attachment, even though the aircraft is stationary.
