Zusammenfassung:The present invention relates to a drone SAR single look complex (SLC) image making method which generates a basic image by synthesizing (duplicating, overlapping) reflected signals continuously received while performing SAR shooting using a drone, corrects the generated basic image with operation information during drone operation and image parameters collected during the drone operation as a medium, and accurately makes an SAR SLC image. The method comprises: an SAR shooting device mounting step of mounting an SAR shooting device (30), a GPS sensor (40), and a navigator (50) to a drone aircraft (10); a basic image generating step in which the SAR shooting device (30) generates a basic image by synthesizing reflected signals continuously received during the operation of the drone aircraft (10) and records parameters of the basic image; and an SLC SAR image generating step in which a data processing device (80) corrects the basic image with the parameters of the basic image and the operation information of the drone aircraft (10) as a medium and generates an SAR SLC image. 본 발명은, 드론을 이용하여 SAR 촬영을 수행하면서 연속적으로 수신되는 반사신호를 합성(중복, 중첩)하여 기초영상을 생성하고, 생성된 기초영상을 드론 운행 시의 운행정보, 드론 운행 시 수집된 영상 파라미터를 매개로 보정하여, 정확한 SAR SLC 영상을 제작하는 '드론 SAR SLC 영상 제작 방법'에 관한 것으로, SAR촬영장치(30)와 GPS센서(40)와 네비게이터(50)를 드론기체(10)에 장착하는 SAR촬영장비 장착 단계와; SAR촬영장치(30)가, 드론기체(10) 운행 중 연속적으로 수신하는 반사신호를 합성하여 기초영상을 생성하고, 기초영상의 파라미터를 기록하는 기초영상 생성 단계 및; 데이터처리장치(80)가, 기초영상의 파라미터와 드론기체(10) 운행 정보를 매개로 기초영상을 보정하여, SAR SLC(Single Look Complex) 영상을 생성하는 SLC SAR 영상 생성 단계 를 포함하는 것을 특징으로 한다.
