Abstract

Devices, systems and methods are disclosed which relate to reproducing and testing a simulation of electromagnetic propagation of multiple Radio Frequency (RF) jammers in an environment to determine the effectiveness of the jammer configuration. In some configurations, a multi-jammer simulator renders the electromagnetic propagation of a multiple jammer scenario, including multiple RF jammers onboard vehicles traveling through the environment, and records a multi-waveform output of the multiple jammer scenario to a recordable medium. A multi-waveform generator reads the multi-waveform output from the recordable medium and physically reproduces a plurality of waveforms consistent with the multi-waveform output. The plurality of waveforms is substantially similar to a physical reproduction of the multiple jammer scenario. An RF receiver, placed within a range of effectiveness of the multi-waveform generator, attempts to receive a signal from an RF transmitter during reproduction of the multi-waveform output. Results are recorded in the form of successes and failures associated with the attempts and compared with results from the simulation.
