Wideband Autocorrelation Radiometry

  • ice thickness location 1 vs 2


Mission: Measuring lake ice and dry snow pack from a distance

Challenge: To overcome the difficulties presented in measuring multiple layers of snow and ice, with such variable properties as snow grain size, without the need to calibrate algorithms for each new terrain.

Solution: Utilizing the time it takes for passive microwaves to propagate through snow and ice offers a low-cost, power efficient, and flexible solution to this problem.

Value: With the changing climate, demand grows for accurate remote-sensing instruments and techniques for monitoring environmental change. In particular, understanding the changing behavior of ice and snow in different regions is vital to effective water supply management.
