The reflection of a transient plane wave, from an ionospheric model with a linear electron‐density profile, is considered. After a discussion of causality and physical realizability, the impulse response is calculated for the special case of no collisions. For this special case, it is shown that the wave form of the reflected wave has a smoothly rising initial portion that is followed by a slowly damped oscillatory portion which comprises the main signal.
