Unprecedented radar performance is now available with the Collins TWR-850/ WXR-840/WXR-800 Weather Radar Systems. State-of-the-art electronic and computer technologies provide operational convenience and features previously available only to large air transport aircraft. Now, the small size and light weight of the TWR-850/WXR-840/WXR-800 make these radars the choice for the rest of the turbine-powered fleet. In addition, the solid-state transmitter improves reliability and eliminates one of the most troublesome components of conventional weather radar - the magnetron vacuum tube.
In addition to the expected function of detecting precipitation, the TWR-850 also detects accompanying turbulence by using Doppler frequency shift. This technological advancement is made possible by the availability of transmitters with extremely high frequency stability and powerful digital signal processing capabilities.
