Paper Abstract
The techniques of signal extracting and processing for remote sensing system are discussed in this paper. We are now developing a ten-band ocean color and temperature scanner for observing the ocean color. Because each spectral bandwidth is quite narrow and the reflectivity of water is very low, it is very important for the sensor to have a high sensitivity. The performance of detector limits the performance of sensor. Two kinds of detector are used in this sensor. The parameters and the operating modes of these detectors are introduces in this paper. Two kinds of preamplifier are also introduced. One is transimpedance amplifier that converts the output current from Si PV detectors to voltage signal. The other is instrument amplifier, which is used to amplify the output voltage of HgCdTe photoconductor. The equivalent input noises of these circuits are analyzed in detail. The parameters of the ten- band sensor are calculated finally.
