یکی از مسائلی که در سیستم sar مطرح می شود مسأله نویز speckle می باشد. منبع تولید نویز speckle فاز نسبی پراکنده گرهای مختلف در یک سلول رادار می باشد که نوسانات شدیدی در سیگنال دریافتی به وجود آورده و تصویر حاصل را دانه دانه می نماید. این نویز تفسیر تصاویر را مشکل و اطلاعات زیادی را مخفی می کند و لذا کاهش آن یکی از ملزومات در پردازش سیگنال sar است. الگوریتمهای متعددی جهت کاهش نویز speckle در نوا...
The recent Mw 6.3 destructive L’Aquila earthquake has further stimulated the improvement of the Italian operational earthquake forecasting capability at different time intervals. Here, we describe a medium-term (10-year) forecast model for Mw ≥5:5 earthquakes in Italy that aims at opening new possibilities for risk mitigation purposes. While a longer forecast yielded by the national seismic-haz...
the investigation of this paper focuses on eastern part of shahroud fault system in middle-east alborz. this fault system is an important part in the seismotectonic map of the area. we used two local temporary dense seismological networks data installed around the fault system for several months during 2007 and 2008 and simultaneously micro-earthquakes data recorded by the permanent seismologic...
the tabriz fault in northwest of iran is the important geological structure in our country which historical earthquakes were recorded around it. the purpose of this paper is the study of tabriz fault seismotectonic activity. the method of research is drawing 23 cross section vertical to tabriz fault between tabriz and bostan-abad distinguish mountain-front faceting, mountain-front sinuosity and...
The 1999 Izmit earthquake (17/08/1999, Mw=7.4) was one of the largest earthquakes in the past 100 years in the northwestern region of Turkey. This earthquake occurred along the Izmit-Sapanca fault within the Northern Anatolian Fault Zone. Variations in the generalized fractal dimensions (Dq) of clustering in time and space, the Gutenberg-Richter b-value, and earthquake frequency (N) are evaluat...
Quiescent faults may be capable of creating catastrophic earthquakes in locations with moderate and/or low seismic activity, such as Egypt. This study combines structural, remote sensing (RS), geophysical, and activity data to examine analyze the relationship between tectonic structures seismotectonic In a new seismo-lineaments map Egypt, lineaments Egyptian mainland were delineated classified....
