一种雷达干扰技术—灵巧噪声干扰

由于脉冲多普勒（PD）雷达采用超低副瓣天线，或者使用相干旁瓣对消器或匿影器等技术，旁瓣干扰会变得极为困难，使得传统的噪声干扰或欺骗干扰的效能大大降低，介绍了一种兼有噪声干扰和欺骗干扰特点的灵巧噪声干扰技术，给出一种该干扰机的组成原理框图，简述了其工作原理并分析了其干扰效能。

Ablation of GaN Using a Femtosecond Laser

We study the pulsed laser ablation of wurtzite gallium nitride(GaN) films grown on sapphire,using the femtosecond laser beam at a central wavelength of 800nm as the source for the high-speed ablation of GaN films.By measuring the backscattered Raman spectrum of ablated samples,the dependence of the ablation depth on laser fluence with one pulse was obtained.The threwshold laser fluence for the ablation of GaN films was determined to be about 0.25J/cm^2,Laser ablation depth increases with the increasing laser fluence until the amount of removed material is not further increased.The ablated surface was investigated by an optical surface interference profile meter.     

Reversible Decoherence of a Mesoscopic Superposition Driven by a Time—Dependent External Field

By using the normal-ordering technique in the coherent state representation,we discuss the dynamical evolution of the coherence of a Schrodinger cat state in a high Q cavity coupled to another resonator in the presence of external fields.During the progression of the coherence,we pay particular attention to the effect of the external fields,as well as to the initial phase of the Schrodinger cat state.
