The Directed Radio Frequency Energy Assessment Model (DREAM) is an engineering/engagement level model that simulates the interaction between a High-Power Radio Frequency/Microwave Directed Energy Weapon (HPM DEW) and a target system and calculates/estimates a target’s probability of electronic upset and/or damage as a function of the HPM DEW power density on target and range. DREAM is primarily used for making pre-test predictions and investigating the HPM DEW concepts.

DREAM runs on modern personal computers (PCs) that use Microsoft (MS) Windows operating systems, such as Windows 7 and now Windows 10. DREAM was originally developed by ARL and SPARTA, Inc under the sponsorship of the Joint Technical Coordinating Group on Aircraft Survivability (JTCG/AS) and ARL. The Air Force Research Laboratory (AFRL) is now the model manager for DREAM. DREAM is now available through the Defense Systems Information Analysis Center (DSIAC) website.

Input

DREAM's primary inputs are a fault tree description of the target system and the basic characteristics of the HPM DEW engaging the target (i.e., the frequency, pulse width, pulse repetition frequency (PRF) power, and antenna gain of the HPM source). It also requires the user to select the type of critical electronic component of interest in the target (i.e. Transistor, Digital Integrated Circuit (IC), etc., the type of Port of Entry (POE) for the HPM to enter the target (i.e., dipole, aperture, etc.)  and the transmission loss from the POE to the component.
