Abstract :
An ionospheric-delay correction model that measures the time of arrival (TOA) of transionospheric electromagnetic pulse (EMP) is presented. The pulse-broadening effect due to ionosphere is incorporated into the ionospheric group delay model to provide more accurate delay correction for measuring EMP TOA. The predictions of the model are compared with laboratory test results for various total electron content. This model also enables us to evaluate the sensitivity of TOA performance to changes in the receiver hardware parameters, e.g. filter bandwidth and the threshold levels in the time-tagging process of the EMP waveform.<>
