Pheromone traps, feeding attractant traps, suction traps, and insect nets will also be tested using free-flying and tethered balloons. The radars operate continuously day and night. A parabolic antenna creates a 1 radar beam width. Radar pulse volumes range from 0.25 km to 1.0 km. The maximum operating range of the WSR-88D is 480 km.
Reflectivity is a measure of the returned radar power.
Spectrum width is a measure of variability of the radial velocity samples within a radar pulse volume. Numerous derived products are available. Polar displays of reflectivity, velocity, and spectrum width are commonly projected on horizontal maps. The WSR-88D makes a 360 azimuthal sweep at one elevation angle before proceeding to the next elevation angle. Four scanning strategies are available for particular applications.
