توجه داشته باشید کتاب پروژه های نجوم رادیو و رادار برای مبتدیان، ویرایش دوم نسخه زبان اصلی می باشد و کتاب ترجمه شده به فارسی نمی باشد. وبسایت اینترنشنال لایبرری ارائه دهنده کتاب های زبان اصلی می باشد و هیچ گونه کتاب ترجمه شده یا نوشته شده به فارسی را ارائه نمی دهد.
نجوم رادیویی و رادار ابزارهای قدرتمندی برای مطالعه شگفتی های جهان هستند، با این حال آنها تمایل دارند ستاره شناسان آماتور را ابهام کنند. این کتاب مقدمه ای جامع برای تازه واردان ارائه می دهد که شامل همه چیزهایی است که برای شروع رصد در طول موج های رادیویی نیاز دارید. این کتاب توسط یک مهندس مکانیک نوشته شده است که در واقع ابزارهای توصیف شده را ساخته و راه اندازی کرده است، این کتاب حاوی انبوهی از توصیه های آزمایش شده و منابع عملی است. این نسخه اصلاح شده از کتاب اصلی 2014 Getting Started in Radio Astronomy یک نمای کلی از آخرین فناوری و تحقیقات، از جمله جدیدترین مدل ها و تجهیزات موجود در بازار و همچنین یک بخش کاملاً جدید در مورد نجوم رادیویی با رادیوهای نرم افزاری (SDRs) ارائه می دهد. ). چهار پروژه مبتدی کاملاً جدید شامل پرتاب سیگنال راداری از ماه، شناسایی شفق و تنظیم رادیوی downlink مورد استفاده فضانوردان در ISS است. این کتاب که نیازی به دانش قبلی، ریاضیات ترسناک و تجهیزات گران قیمت ندارد، به عنوان یک مرجع سرگرم کننده و قابل هضم برای هر سطحی از ستاره شناسانی خواهد بود که امیدوارند مهارت های خود را در طیف رادیویی گسترش دهند.
Radio and radar astronomy are powerful tools when studying the wonders of the universe, yet they tend to mystify amateur astronomers. This book provides a comprehensive introduction to newcomers, containing everything you need to start observing at radio wavelengths. Written by a mechanical engineer who has actually built and operated the tools described, the book contains a plethora of tested advice and practical resources. This revised edition of the original 2014 book Getting Started in Radio Astronomy provides a complete overview of the latest technology and research, including the newest models and equipment on the market as well as an entirely new section on radio astronomy with software-defined radios (SDRs). Four brand-new beginner projects are included, including bouncing a radar signal off the Moon, detecting the aurora, and tuning into the downlink radio used by astronauts aboard the ISS. Requiring no previous knowledge, no scary mathematics, and no expensive equipment, the book will serve as a fun and digestible reference for any level of astronomers hoping to expand their skills into the radio spectrum.
