1.1 This test method covers the determination of resonances unpackaged products and components by means of horizontal linear sinusoidal motion applied at the surface on which the product is mounted. For vertical vibration testing of products see Method D3580. Two alternate test methods are presen...

An on-line blind source separation (BSS) algorithm is presented in this paper under the assumption that sources are temporarily correlated signals. By using only some of the observed samples in a recursive calculation, the whitening matrix and the rotation matrix could be approximately obtained thro...

The analytic representation of the transient radiation for an aperture excited by a rectangle pulse is obtained. It shows that the field duration and amplitude depend on the observation distance, the elevation angle, the pulse width of the rectangle pulse and the aperture size.

The interrupted sampling repeater jamming (ISRJ) is an effective deception jamming method for coherent radar, especially for the wideband linear frequency modulation (LFM) radar. An electronic counter-countermeasure (ECCM) scheme is proposed to remove the ISRJ-based false targets from the pulse comp...

The movement of waves propagating over a horizontally submerged perforated plate with waterfilled chambers bellow the plate was investigated by using linear potential theory. The analytical solution was compared with laboratory experiments on wave blocking. The analysis of the wave energy dissipatio...
