A current problem of interest in the Electronic Counter-Measures field is the deception of monopulse type radars. The operational evaluation of any deception device requires that some preliminary work be accomplished in order to establish what electronic devices are most suitable for the job and what specific parameters these devices must meet. This paper investigates the feasibility of installing a monopulse deception repeater on board a steel-hulled ship, the RV ACANIA. The specific parameters investigated are the peak power required for deception and the electronic gain required of the repeater loops. Prior to calculation of these parameters it was necessary to determine the radar cross section of the ship test platform and to measure the antenna isolation to insure its adequacy to prevent destructive feedback of the repeater loops. Successful completion of these experiments enable one to specify that a traveling wave tube amplifier with a power output of 60 dBM and a gain of 52 dB would be an appropriate device for the loop amplifiers.
