TABLE OF CONTENTS A general-purpose, multifrequency mechanically scanned radiometer system has been described. The major characteristics of the system are:
Orbit height: 800 km;
Swath width: 1,498 km;
Polarization: H and V;
Incidence angle: 53 ;
Antenna aperture: 1 m;
Antenna rotation rate: 24 RPM;
Radiometric dynamic range: 0 313K.
Further specifications are found in Table 13.12. Twelve total power receivers are used, and the system requires the following resources:
DC power: 39W;
Weight: 34 kg.
