The power spectrum of backscattered radiation from an underdense turbulent re-entry wake illuminated by a train of short radar pulses can be significantly affected by pulse shape and by exponential decay of the mean electron density, as well as by the finite extent of each pulse (Which limits the exposure time of any coherent wake target under observation). Expressions for the power spectrum and its broadening by these effects are derived and discussed.
