Abstract: 본원발명은 지상전투차량에 탑재된 두 개의 조준경중 하나의 조준경에만 레이저거리측정기가 있는 지상전투체계에서 두 조준경의 조준점 공간 동기화를 이용한 거리측정방법으로서, 상기 두 개의 조준경간의 각도 차 및 조준경 장착위치에 의하여 발생한 시차보상을 적용하여 두 조준경의 조준점을 정밀하게 동기화시켜줌으로써, 차장이 차장조준경을 보면서 조준을 하고 차장핸들의 레이저발사 스위치를 누르면 사수조준경을 차장조준경에 공간적으로 정밀하게 동기화시켜서 거리를 측정하고 차장영상전시기에 전시하여 내부적으로는 사수조준경의 레이저거리측정기가 동작하지만 차장조준경에 레이저거리측정기가 장착되어 있는 것과 동일하여 승무원실 공간활용 및 양산가를 줄일 수 있는 효과가 있다.

Abstract: PURPOSE: A FMCW radar and an attenuating method for a near distance clutter signal of the FMCW radar are provided to expand a dynamic area of a receiver and to improve a signal to noise ratio. CONSTITUTION: A FMCW radar and an attenuating method for a near distance clutter signal of the FMCW radar comprise the following: A RF transmitter(20) is delivered a signal from a signal generator of a frequency generator(30) and transmits the same to a transmitting antenna. The transmitting antenna transmits an RF detection signal to the outside. An RF receiver(10) RF-converts the reflected signal returning from a target and produces the same to a mixer(35). The mixer mixes the local signal separated from the frequency generator and the reflected signal from the RF receiver and produces an intermediate frequency. An intermediate frequency signal amplifier lowers or amplifies the frequency of the Doppler reflected signal and provides the same to a signal processor(70). The signal processor converts the analog signal passed through the intermediate frequency signal expander to the digital signal and extracts the characteristics of the detected target.
