딥네트워크 :: 합성개구레이더(SAR) 도플러 효과 동작원리 분석 전문기업일인기업 딥네트워크는 SAR 위성 기술을 통해 지상의 특정 지점에서 반사되어 돌아오는 신호의 위상을 측정하고, 이를 통해 거리에 비례하는 위상 변화량을 정확하게 보정하는 설계를 구현합니다. 이 과정은 복잡한 신호 처리 알고리즘과 정밀한 계산을 필요로 합니다. 다음과 같은 SAR 위성에서 Raw Radar Data 를 처리하는 핵심 원리 노하우 확보 성공Range Compression (거리 압축)SAR 시스템은 펄스 압축 기술을 사용하여 거리 해상도를 향상시킵니다.송신된 펄스는 특정한 ‘chirp’ 신호로 변조되어, 각각의 반사 신호가 독립적인 주파수를 가지게 됩니다.수신된 신호는 매치드 필터를 통과하여, 각 반사점의 거리에 따른 ..
DeepNetwork :: Synthetic Aperture Radar (SAR) Doppler Effect Operation Principle Analysis Specialist Company DeepNetwork, a one-person company, implements a design that accurately corrects phase changes proportional to distance by measuring the phase of the signal reflected from a specific point on the ground through SAR satellite technology. This process requires complex signal processing algor..
I am 60 years old this year… I have been working in the field of Information and Communication Technology (IT) for 30 years… For the past 10 years, I have been a self-employed individual providing development services in the firmware sector of IT… I am going to talk about life in today’s world after 30 years of social life… From now on, I have been reviewing and analyzing 2-3 papers related to L..
Hello, I am Seokwon Jang from DeepNetwork, specializing in technical consulting for the lightweight implementation of ultra-large language models. I have been examining the status of Korean ultra-large model development companies (mainly large corporate AI research institutes) through articles. Implementing an ultra-large language model also requires preparing a massive amount of precise trainin..
I have finally succeeded in understanding the theory of Kalman filters, which are applied in missile attitude control or robot attitude control. It’s been almost 2 years since I started analyzing this. Everything was so complicated due to difficult technical terms and complex formulas. After about a thousand trials and errors, I am delighted that all the things that were curious and unresolved h..
