The spatial and temporal distributions of snow depth on Tibetan Plateau are revealed by comparing the data retrieved
from satellite remote sensing i.e. SSMR and SSM/I with station observations. All of the results show that snow depth on
the Tibetan plateau plays an important role in East Asia summer precipitation anomalies and in consequence, some
possible mechanisms are proposed.
This paper considers the application of adaptive array antenna based on the least squares constant modulus algorithm
(LSCMA) for interference rejection in mobile SATCOM terminals. A two-element adaptive array scheme is
implemented with a combination of ADI TS201S DSP chips and Altera Stratix II FPGA device, which makes a
cooperating computation for adaptive beamforming. Its interference suppressing performance is verified via Matlab
simulations. Digital hardware system is implemented to execute the operations of LSCMA beamforming algorithm that
is represented by an algorithm flowchart. The result of simulations and test indicate that this scheme can improve the
anti-jamming performance of terminals.
