The embodiments provide a radio frequency signal transceiving device for a synthetic aperture radar which can be mounted on an unmanned aircraft, which can restore an accurate SAR image corresponding to an antenna position at the time of transmission by using a clock signal synchronized with a 1PPS signal of a satellite navigation module, and a method thereof. The radio frequency signal transceiving device includes a satellite navigation module, a synchronization oscillator, a first divider, a first oscillator, a second oscillator, a digital frequency synthesizer, a transmission unit, a third oscillator, a reception unit, a second divider, a rectifier, an analog to digital converter, a storage unit, and a SAR processing unit.
본 실시예들은 위성 항법 모듈의 1 PPS 신호와 동기화된 클록 신호를 이용하여 송신 시점의 안테나 위치에 대응하는 정확한 SAR 영상을 복원할 수 있는 무인 비행체에 탑재 가능한 합성 개구 레이더용 무선주파수 신호 송수신 장치 및 방법을 제공한다.
