Changing Requirements For EW Threat Simulation
Abstract
This paper represents my own observations based on recent procurement and contract activity engaged in by Amherst Systems. It is not the result of a scientific survey. No requirement is intended to be associated with a specific system under test or program. These observations are based on many recent requests for proposals and contracts which Amherst Systems has been exposed to. As a leading manufacturer of EW threat simulators for all applications (RWRs, Jammers, ELINT receivers, etc.), Amherst Systems is in a unique position to be aware of many current and future requirements. While we have not won every contract, we have had the opportunity to bid on every major program and thus have been exposed to the most stringent simulation requirements. An EW threat simulator performs three basic functions. The first step is the generation of the radar's transmit waveform. This requires the generation of an RF waveform with the appropriate PRI, frequency, pulse, and scan characteristics. This waveform represents the RF signal as it leaves the transmit antenna. The second function is the modeling of the environmental effects as the waveform travels from the transmitter to the receiver. This model takes into account all factors which affect the electromagnetic wave as it travels from the transmit antenna to the receive apertures on the system under test. The final step is to model the aperture and receiver effects as the waveform is measured by the system under test.
