Webquasiperiodic echo structure were observed with the coherent scatter radar. In six of those events, simultaneous measurements were made with the Arecibo 430-MHz incoherent scatter radar. The imaging coherent scatter radar allows us to locate and track the echo structures within the volume illuminated by the transmitter, which shows structures WebMillstone Hill UHF incoherent scatter radar system. The current centerpiece of the Millstone Hill facility is its high-power, large-aperture incoherent scatter radar (IS radar) facility. This radar system consists of two 2.5 MW UHF transmitters, a fully steerable 46 m diameter antenna, and a fixed zenith directed 68 m diameter antenna.
