Plasma gradients at magnetopause are too small to reflect radiowaves
Small scale irregularities make specular reflection impossible
High plasma velocities in magnetopause will destroy the processing gain of spectral coherent integration
Ionospheric experience shows echoes for (?n/n)-1 > 104 km
RPI is designed to measure specular coherent reflections, non-coherent reflection and coherent scatter. Similar to equatorial and auroral ionospheric sounding
Different waveforms and processing techniques maintain high processing gain for up to 750 km/sec velocities
