The invention discloses a distance-speed synchronous pull-off deception jamming recognition algorithm based on gradient projection, and belongs to the field of radar anti-jamming. According to a PD radar, the radar is generally jammed through distance-speed synchronous pull-off jamming, the deception jamming can conduct pull-off jamming on distance information and speed information at the same time, and thus the difficulty for accurately choosing and tracking a target of the PD radar is increased. The method comprises the following steps that (1) signals received by the radar are sampled, and a complete atom library is established according to the time-variant characteristic of a distance-speed synchronous jamming echo; (2) when the AGC voltages and the target number of a receiver are suddenly changed, it is judged that the target is jammed; (3) the Doppler frequency of the target is obtained through a gradient projection method, then the target speed is figured out, and accordingly anti-jamming is performed according to the target speed. The distance-speed synchronous pull-off deception jamming recognition algorithm based on gradient projection is high in jamming recognition capability, easy in engineering realization, high in engineering application value and large in popularization prospect.

Composite tooling is fabricated with low cost dry fabrics and a neat resin instead of expensive prepregs. Dry, three-dimensional woven joint preforms are placed on a dry tool substrate and dry, 3D preforms are also placed between pre-cured egg crate-like junctions. The entire tool substrate and substrate-to-support structure joints are then resin-infused simultaneously through the use of rota-molded tooling aids, providing an additional reduction in cost. Tight control of resin content and distribution with vacuum infusion is thereby provided. This process eliminates the primary cause of structural weakness and cooling distortion, which typically occur at the attachment interface when existing methods are used. The preforms provide significantly greater pull-off strengths at interfaces than do hand-laid tie plies. Issues with tool surface durability are addressed through the use of ceramic-filled face coat.

A musical instrument is comprised of a keyboard, a strummer, and a processor. The keyboard and strummer send event messages to the processor whenever a key is pressed, or a string is plucked, respectively. At the time a string is plucked, the processor dynamically assigns a note to the string, based on which keys are depressed. The dynamic note assignment ensures that the top, or a predefined string is part of any selected chord or scale passage. In response to strummer and keyboard events, the processor selects different timbres or articulations of the note including: clean, thumb harmonics, muted, hammer-on, or pull-off. The processor plays back recorded samples or synthesized tones to emulate the sounds of different playing techniques on an acoustic, electric, bass guitar or other stringed instruments.
