Description and demonstration of the new Middle and Upper atmosphere Radar imaging system: 1‐D, 2‐D, and 3‐D imaging of troposphere and stratosphere

The Middle and Upper atmosphere Radar (MUR) was upgraded in March 2004 for radar imaging capability with 5 frequencies across a 1 MHz bandwidth and 25 digital receivers. Although digitization introduces problems of its own, the uniformity of digitization is a great benefit over the analogue system in place before. This increased reliability will help make the new system an important component of long‐term atmospheric science programs. We demonstrate 3‐D imaging with Capon's method, which can provide information about structure morphology. In addition, we demonstrate an experimental 0.5 μs pulse mode and compare this to Capon method imaging results.
