강우 탐색을 위한 빠른 스캔과 비가 오는 지역에 대한 일반 또는 집중 스캔을 사용하는 우주 강우 레이더 적응형 스캔의 성능을 TRMM(Tropical Rainfall Measurement Mission) 강수 레이더(PR) 데이터를 이용한 시뮬레이션을 통해 연구합니다. . 강우 누락 및 강우 지역의 오경보를 최소화하기 위한 최적의 빠른 스캔 및 강우 탐색 방법을 찾기 위한 트레이드오프 연구를 수행합니다. 이렇게 결정된 최적의 방법을 사용하여 연속 8일간의 TRMM PR 데이터를 사용하여 감도 향상 및 전력 소비 절감 측면에서 적응형 스캔의 성능을 통계적으로 평가합니다. 유효 신호 대 잡음비가 3dB 이상 개선된 것으로 나타났습니다(SNe)는 전체 관측치의 40%에 대해 달성될 수 있습니다. 또는 다음과 같은 경우 약 26%의 절전 효과를 얻을 수 있습니다. SNe 동일하게 유지됩니다.

Abstract: The performance of the adaptive scan for spaceborne rain radar, which uses a quick scan for rain search followed by a normal or concentrated scan only for rainy areas, are studied through a simulation using TRMM (Tropical Rainfall Measuring Mission) Precipitation Radar (PR) data. Trade-off studies are performed to find an optimum quick-scan and rain search method to minimize rain missing and false alarm of rain area. Using the optimum method thus determined, consecutive 8-day TRMM PR data are used to statistically evaluate the performance of the adaptive scan in terms of sensitivity improvement and power consumption saving. It is shown that more than 3-dB improvement in effective signal-to-noise ratio (SNe) can be achieved for 40% of the total observations. Alternatively, about 26% power saving can be achieved if the SNe is kept the same.
