چکیده | ||
چکیده: در این مقاله، مسئله طراحی شکلموج به منظور تخمین پارامترهای تأخیر و داپلر هدف، بر اساس معیار [i]CRB بررسی میشود. پس از به دست آوردن حدود CRB، از مدل سیگنال OFDM برای طراحی شکلموج استفاده میشود و با حداقل کردن این حدود دو شکـلمـوج طراحی میشود. کارآیی شکلموجها نیز با استفاده از تابع ابهام متقابل(CAF[ii])، مورد بررسی قرار گرفته و برای ارزیابی دقیقتر از پـارامتر MF[iii] استفـاده میشود. افزایش مقادیر MF، معادل افزایش احتمال آشکارسازی هدف در رادار است. نتایج شبیهسازی نشان میدهد که با استفاده از شکلموجهای طراحیشده، میزان MF افزایش مییابد که این امر بیانگر کاهش پیکهای فرعی در تابع CAF و درنتیجه افزایش احتمال آشکارسازی هدف است. | ||
