JZM-Ku1 pulse-modulated scanning air-borne scatterometer

JZM-Ku1 airborne scatterometer works in the Ku-band with a pulse-modulated transmitting probe, conically scanning pencil beam and dual-polarization antennas. Digital signal processing is employed in this instrument to improve the measurement stability, accuracy and speed. This scatterometer is very suitable for backscatter coefficient measurements over land and sea. In the second part, some of the experimental results of sea surface wind were presented. Compared with the actual wind (synchronously collected by weather and hydrology survey instruments on ship), the wind direction deviation is less than 12 degree, and the wind speed deviation is less than 10%. This radar is also suitable for observation of forests, crops and soil moisture and salinity.
