چکیده

روش رادار نفوذی به زمین (GPR) قابلیت ارائه تصاویر با تفکیکپذیری زیاد از زیر زمین را دارا است اما تفسیر درست پاسخ اهداف مددوو در
زیر سطح و ساختارهای زمین، مستلزم شناخت و آگاهی از پاسخ انواع مختلف اهداف زیرسطحی میباشد. یکدی از متدداول تدرین ندوع اهدداف
مدوو زیرسطحی، اهداف استوانهای اوقی همانند انواع لولهها، کانالها، تونلها و قناتها میباشند. در پژوهش حاضدر از مددل سدازی ددددی
پیشرو به روش تفاضل محدود دوبعدی، به منظور شبیهسازی پاسخ GPR مدلهای مصنودی استوانهای شکل اوقی براسدا شدرایم مختلدف
متناظر با واقعیت استفاده شده تا در تفسیر نگاشت راداری برداشتهای واقعی مورد استفاده قرار گیرند. در نهایت، آشکارسازی موقعیدت یدک
قنات مدوو واقع در شمالغرب شهرستا شاهرود به دنوا مطالعه موردی این پژوهش، کارایی روش GPR را بدرای ایدن منظدور بده ا بدات
رسانده است.
