EMI SURVEY FOR MARITIME SATELLITE 1535 EN DASH 1645-MHZ SHIPBOARD TERMINAL

This paper discusses measurements and results of an EMI survey conducted onboard a commercial U. S. maritime vessel to determine compatibility for operation of a satellite L-band shipboard terminal. In general, the EMI survey reveals tolerable interference levels onboard ship: radiometer measurements indicate antenna-noise temperatures less than 70 K, at elevation angles of 5 degree and greater, at 1559 MHz, at the output terminals of the 1.2-m diameter, parabolic-dish antenna for the L-band shipboard terminal. Other EMI measurements include field intensity from 3-cm and 10-cm wavelength pulse radars, and conducted-emission tests of primary power lines to both onboard radars.
