受動地球観測センサ性能の統一的解釈

抄録

We constructed mathematical models of passive earth observation sensors common between optical imagers and microwave radiometers based on generic interpretation along with a sequence of functional blocks, namely the signal chain. These mathematical models were used to estimate the performance of main sensors, particularly such factors as spatial resolution and the signal-to-noise ratio (SNR). Moreover, these mathematical models were applied to existing sensors and their estimated performance was compared with and validated by the known sensor performance described in the literature. Such generic interpretation will make it possible to systemize the various types of earth observation sensors.
