Cross validations of radio-frequency interference signature in AMSR-E data using two detection methods

metrics for the detection of changed buildings in 3d old vector maps using als data (case study: isfahan city)

هدف از این تحقیق، ارزیابی و بهبود متریک های موجود جهت تایید صحت نقشه های قدیمی سه بعدی برداری با استفاده از ابر نقطه حاصل از لیزر اسکن جدید شهر اصفهان می باشد . بنابراین ابر نقطه حاصل از لیزر اسکنر با چگالی حدودا سه نقطه در هر متر مربع جهت شناسایی عوارض تغییر کرده در نقشه های قدیمی سه بعدی استفاده شده است. تمرکز ما در این تحقیق بر روی ساختمان به عنوان یکی از اصلی ترین عارضه های شهری می باشد. من...

Radio Frequency Interference and Detection of Fast Radio Transients

Exploring the transient radio sky is one of the major science drivers for several upcoming and planned radio telescopes, including the Square Kilometer Array (SKA). The detection of transient signals, particularly of relatively short durations, can however be considerably hampered by the prevalent and ever growing problem of radio frequency interference (RFI) in radio astronomy. With the goal o...

Radio frequency interference detection and mitigation techniques using data from EcoSAR 2014 Flight Campaign

Radio frequency interference (RFI) has strong influence on wide band airborne radar systems, especially operaing at L-band (1-2 GHz) or lower frequencies. EcoSAR is a P-band digital beamforming radar system, and RFI has to be removed from raw echoes to obtain science quality data. In this paper we describe the current methodology used to tackle RFI with EcoSAR, and provide an example on its per...
