Summary
  • Spaceborne wind scatterometers are designed principally to measure radar backscatter from the ocean's surface for the determination of the near-surface wind direction and speed. Although measurements of the radar backscatter are made over land, application of these measurements has been limited primarily to the calibration of the instrument. This has been due in part to the low resolution of the scatterometer measurements (nominally 50 km for the Seasat-A Scatterometer [SASS]). In this paper we present a method for generating enhanced resolution radar images of the earth's surface using spaceborne scatterometry. The technique is based on a new image reconstruction technique which takes advantage of the spatial overlap in scatterometer measurements made at different times to provide enhanced imaging resolution. We describe the reconstruction algorithm and demonstrate the technique using both simulated and actual SASS measurements. The technique can also be used with ERS-1 scatterometer data. The SASS-derived images, which have approximately 4 km resolution, dramatically illustrate the resolution enhancement capability of the new technique. The technique permits utilization of both historic and contemporary scatterometer data for medium-scale monitoring of vegetation and polar ice. We discuss the tradeoff between imaging noise and resolution inherent in the technique. The instrument processing method employed by SASS limits the ultimate resolution which can be obtained with our method. However, with minor modifications to future Doppler scatterometer systems (such as the NASA scatterometer [NSCAT] and its follow-on EoS-era scatterometer) imaging resolutions down to 1-2 km for land/​ice and 5-10 km for wind measurement can be achieved with a moderate increase in downlink bandwidth (from 5 kbps to 700 kpbs). We describe these modifications and briefly describe some of the applications of this medium-scale K u-band imagery for vegetation studies, hydrology, sea ice mapping, and the study of mesoscale winds.
