Airborne distributed coherent aperture radar is of great significance for expanding the detection capability system. However, extra observation dimension introduced by its sparse configuration also deteriorates performance traditional adaptive processing in a non-uniform environment. This paper focuses on moving target when system works clutter–jamming-coexisting In order to make full use speci...
We report here on a rare case of lipoma in the deep lobe of the parotid gland. MRI revealed that the tumour was situated mainly in the deep lobe and it extended posteriorly and medially into the space between the sternocleidomastoid muscle and the posterior belly of the digastric muscle, with slight extension into the parapharyngeal space. This tumour produced strong signals on T1- and T2-weigh...
Abstract For the sky-wave over-the-horizon radar (OTHR), how to effectively suppress radio frequency interference (RFI)from main-lobe direction is a problem. To solve this problem, paper proposes new space-fast time adaptive processing (fast-time STAP) which merges matched filter coefficients used for pulse compression and steering vector of fast-time STAP. compare with conventional methods, me...
The role of classical neurotransmitters in the transfer and processing of olfactory information is well established in many organisms. Neuropeptide action, however, is largely unexplored in any peripheral olfactory system. A subpopulation of local interneurons (LNs) in the Drosophila antannal lobe is peptidergic, expressing Drosophila tachykinins (DTKs). We show here that olfactory receptor neu...
New parasitic lasing suppression techniques are developed and high gain amplification is demonstrated in a petawatt level Ti:sapphire amplifier based on the chirped pulse amplification (CPA) scheme. Cladding the large aperture Ti:sapphire with refractive-index matched liquid doped with absorber suppresses the transverse lasing. The acousto-optic programmable dispersive filter (AOPDF) is used to...
