Abstract : An ASR-5 Weather Clutter Feasibility Model was developed and evaluated to provide Air Traffic Controllers with a weather display (clutter free) of air traffic and a contour depiction of weather detected by radar. The technical tests included the determination of technical characteristics of each of four modifications (narrow transmitter pulse width, noncoherent moving target indicator, dual frequency diversity, and logarithmic/fast time constant) which comprised the weather rejection portion of the system along with their capabilities to provide clutter rejection and target detection in weather. The four modifications were then tested in unison to determine the system's overall capability. The weather channel portion of the equipment was tested to determine its capability to provide weather clutter formatting in the form of isoamplitude contours. (Modified author abstract)
