High power HF radiowave pulses launched from ground-based transmitters interact with overdense quies-cent ionospheric plasma to produce strong turbulence effects. These effects are evident in the ion and plasma lines detected by diagnostic radars. Several spatial and temporal signatures in the backscattered plasma lines show reproducible evidence of strong turbulence effects at many scales. Complementary to radar probe diagnostics are stimulated electromagnetic emissions (SEE) which propagate to HF receivers on the ground. Many experiments using SEE receivers have been performed using relatively long (seconds) HF pulses. Long HF pulses are sufficient to produce irregularities and turbulence at several scales incorporating many effects. We report a series of experiments performed at HAARP (Gakona, Alaska) using both radar and SEE diagnostics together with a range of HF pulse widths down to ten mil-liseconds. Using short HF pulses, we are able to discriminate, characterize, and compare prompt SEE spectra over the time-scales of typical radar features. We present the results of numerical simulations modeling the development of strong short-scale turbulence and mesoscale irregularities for comparison with these experiment
