发明名称 DETERMINING A TRANSMITTER RADIO-FIELD COVERAGE
摘要 <p>The invention concerns a method whereby the radio-field of a transmitter (S) is measured in real points (PMRj) on a digitised geographical map. For each geographical point (PGi), a maximum variation (VGPi) of a physical quantity, altitude or radio-field, is determined (E4) about the point. The distance (Di) of a measuring point (PMi) nearest to the geographical point is evaluated (E5). A physical quantity interval containing the variation (VGPi) is sought (E6, E10) among several associated with distances. The geographical point (PGi) is rejected when said distance is less than the distance associated with the interval, or is accepted as fictitious measuring point (PMF) to increase the number of measuring points in an uneven zones. The radio-field in each geographical point is deduced (E12) from the fields at the real and fictitious measuring points and from the distances between them and the geographical point to visualise without aberration coverage zones.</p>
