The report describes a hollow spherical dipole D-dot sensor model HSD-4. It consists of two hemispherical conducting shells on opposite sides of a ground plate and produces a current output in response to a time-variant D-field perpendicular to the ground plate. The sensor is a scaled-down version of a larger hollow spherical dipole model HSD-2, but with less sensitivity and higher frequency response. The theory of operation design, and construction of the sensor, and prototype testing and test results are discussed.
