Effects of an Irregular Ionosphere on L-Band Radar System

Abstract

The change in apparent range between an L-Band Radar System and a high flying target introduced by a traveling ionospheric disturbance (TID) is calculated. Using an ambient Chapman electron density profile perturbated by a realistic TID model, the excess propagation time delay is determined by the use of ray-tracing techniques. For a fixed frequency, the variable component of group delay due to these irregularities is dependent on the direction of TID travel relative to the propagation path and the elevation angle. Numerical results for a typical case are represented.
