Radiation intensity for the approach radar at ´N. Kazantzakis´ airport, Heraklion, Crete

Summary form only given. The growing interest in potential health effects associated with public exposure to electromagnetic (EM) radiation has placed a great number of issues related to safety standards and moreover the appropriate measurement procedures as well as the instruments used. Especially, EM pulsed sources producing large amount of EIRP like radars at civil airports, it is of vital importance to be measured for the purpose of mapping the EM pollution in the nearby residential areas. The paper presents a detailed measurement procedure as well as a set of measurements carried out in the vicinity of the approach radar installed in ´N. Kazantzakis´ airport at Crete, Greece. The methodology of near-intermediate-far field calculations is presented as an initial estimation of the expected values. Since the nominal characteristics of the radar were known the measurement apparatus was calibrated for the best possible parameter extraction for both the primary and secondary radar including pulse width, pulse repetition frequency, power density spectrum, power density of the un-modulated carrier etc. A measurement procedure of the RF pulsed sources is given in detail with extra attention to measurement repeatability and reliability. The measurements took place in three sites and their selection was based primarily in the population density in the vicinity of the radar. The results are compared with the European EM safety standards that have been approved and adopted in Greece. Finally, for comparison reasons of the measured results with the theoretical ones a number of propagation models are taken into account
