Abstract :
The authors describe a computationally simple multiquasiparabolic (MQP) model which is largely defined in terms of standard scaled ionospheric parameters. The model gives analytic expressions for ground range estimation. Its results compare favourably with those obtained using numerical ray-tracing through a Dudeney ionosphere. In its present form the MQP model is suitable for use in operational single site location HF direction finding systems at geomagnetic mid-latitudes.<>
