A Portable Multiband Radiometer and Its Application

The radiometer is a portable battery operated instrument, consisting of two main parts: optical head and processing unit. The optical head is equipped 6 channels between 0.4 and 2.5 micrometer, which may match with MSS, TM bands, and others. It is easy to change the FOV and passband filter of channels in field conditions by modular design. The processing unit records and processes the data from the optical head, it's foundmental component being a microprocessor. The system is adaptable to helicopter, truck or tripod platforms, it is also suitable for hand-hold operation.The general properties of the system are:1. comparatively inexpensive to acquire, maintain and operate,2. simple to operate, calibrate and service,3. rapid measurement ability,4. complet with data handing, processing hardware and softwre.Some results of application are shown, which has proved that the system can be utilized by many researchers to obtain large numbers of accurate, calibrated spectral measurements for remote sensing.
