Radar Detection of High Concentrations of Ice Particles - Methodology and Preliminary Flight Test Results 2019-01-2028
High Ice Water Content (HIWC) has been identified as a primary causal factor in numerous engine events over the past two decades. Previous attempts to develop a remote detection process utilizing modern commercial radars have failed to produce reliable results. This paper discusses the reasons for previous failures and describes a new technique that has shown remarkable accuracy and range performance. The performance of this new process was evaluated during the joint NASA/FAA HIWC Radar II Flight Campaign in August of 2018. Results from that evaluation are discussed, along with the potential for commercial application, and development of minimum operational performance standards for future radar products.
