An X-Y plot is made of the radiated electromagnetic signals and noise between 1 KHz and 50 KHz at each of the four Personalized Rapid Transit (PRT) sites at Dulles International Airport. The PRT systems were operated individually to establish the signal characteristics of each system. A spectrum analyzer was used to view the frequency spectrum broadband prior to recording and a Polaroid scope camera was used in conjunction with the spectrum analyzer to photograph signals between 50 KHz and 50 MHz. This frequency range was sufficiently broad to cover all command and control frequencies of the four PRT systems. The purpose of the measurements program was to establish some base line information on the electromagnetic signal characteristics in the Dullas area in the event there was an interaction between the PRT Command and Control systems and the Federal Aviation Administration Air Traffic Control equipment. The measurements obtained during this series of tests will be used for a comparison with data obtained with no PRT systems operating and later with all four systems operating simultaneously.
