Mathematical Modeling of Efficacy of Ground-based Jamming Operation against Airborne GPS Receiver

As the smart guided weapons, such as Cruise Missiles, are using GPS navigational information to correct their inherent internal errors, their onboard GPS receiver is the main target of most electronic warfare operations. To model the efficacy of EW operation, the problem of calculation of received jamming power by onboard GPS receiver simplified, using Worst Case Conditions. The flight profile receiver antenna’s radiation pattern are modeled mathematically to calculate the AoA of jamming signal. These models have been used to develop a simulation software. Based on three different scenarios, the results have illustrated figuratively vulnerability of DH OH scenarios were found.
