Abstract
An apparatus for use in evaluating the effectiveness of an ECM technique, such as the Cross Eye technique, which transmits RF signals from spatially separated antennas against a hostile radar system, such as a monopulse radar. The invention splits the radar transmit RF signal into separate paths, applies the ECM signal, and calibrates the combined radar-ECM signal for phase and amplitude balance after every pulse repitition interval. The signal is down converted to an intermediate frequency where a radar receive antenna is simulated. Following the antenna, an injection network up converts the frequency of the signal and adds computer controlled inputs (including echoes) prior to sending it to the radar receiver for final processing.
