Abstract
It has been previously shown [1] that the Parabolic Equation (PE) technique is well suited to solving GPS propagation problems over large domains. This paper presents the results of a modified model, which includes the effects of backscatter and provides time-domain representation of the propagated GPS signal. Results are presented for various difficult GPS propagation environments, including the determination of the Multipath Channel Impulse Response (MCIR) from the PE.
