  • Project Problem StatementforThe National Weather Service Radar Operations Center Captain Colin M. JohnstonThe goal of the WSR-88D Capstone Project is to implement a higher order model to more closely simulate actual radar movement, velocity and acceleration and still return data packets to the command module at the required frequency.

  • Project Compliance2nd order simulation of radar movementBoth Elevation and AzimuthMeets SpecificationsRise Time < 1 secondSettle Time < 2 secondsSteady State error < 5%Accommodates physical limitation of radar dishMaximum speed 6 rad/s 36/secondElevation Range -2 to + 60Elevation hard stops eventually cause errors
