An advanced weather radar system can project weather conditions ahead of an aircraft by applying DSP to multiple radar returns.
The United States (US) Coast Guard has selected Rockwell Collins to provide the MH-65E Radar Sensor System (RSS) for 102 MH-65E aircraft. The solution will feature Rockwell Collins’ RTA-4114 MultiScan Weather Radar with enhanced ground/shoreline mapping and a new maritime surface search mode. Per the contract, Rockwell Collins will provide an enhanced RTA-4114 radar for shoreline and over-water use. According to Troy Brunk, the firm’s vice president and general manager of airborne solutions, “Coast Guard pilots will benefit from MultiScan’s broad array of capabilities that provide reduced workload and enhanced situational awareness. MultiScan’s solid-state design provides high reliability and reduced life cycle costs that are vital in a cost-constrained budget environment.”
The RTA-4114 MultiScan Weather Radar system automatically scans ahead of an aircraft and combines radar returns through advanced digital signal processing (DSP) and analysis algorithms to display not just precipitation rates, but actual weather threats. The weather radar system features automated tilt, clutter removal, and gain management, and performs automatic compensation for predictable atmospheric and climatic conditions.
