Tropical radar environmental information system (TREIS) is a concept for a system of tropical forest monitoring based on satellite radar remote sensing. The approach is novel--starting from the ground up. TREIS offers a way around three major obstacles that are likely to preclude large-scale use of currently planned space radars: (1) high primary data cost; (2) complex and centralized ground segment infrastructure; and (3) a less than optimum radar wavelength. The proposed system is specified based on existing regional capabilities in data reception, processing, and utilization. The space segment uses existing AVHRR class data telemetry (625 Kbps), and partial on-board preprocessing of the P-band (75 cm) synthetic aperture data. Aggregate coverage of the earth''s tropical forests twice a year is achieved with ten look imagery of 20 km usable swath width and pixel spacing of 50 m. Image processing requires only work stations or high-end PC-class hardware which could be distributed over many regional centers. Data products could be prepared rapidly and inexpensively for regional use and for global inventory efforts such as those of the United Nations.
