EWA GSI’s ELINT Proficiency Trainer provides signal recognition training based on signal characteristics and signal audio. The trainer can be hosted on stand alone PC(s) or used in a network environment for classroom training. EWA GSI’s Electronic Warfare Scenario Simulator (EWSS) provides the desired signal environment. Each signal is scripted in the EWSS software by entering pulse characteristics, frequencies, scan pattern, scan time, beam widths in both the horizontal and vertical plain, and sidelobes if desired.
