ITU-R M.1851 SPANISH-2009 用于干扰分析的无线电测定雷达系统天线图的数学模型

This Recommendation describes radiodetermination radar systems antenna patterns to be used for singleentry and aggregate interference analysis. Given knowledge about antenna 3 dB beamwidth and first peak side-lobe level, the proper set of equations for bothazimuth and elevation patterns may be selected. Both peak, for single interferer, and average patterns, for multiple interferers, are defined.

Question ITU-R 234/8 calls for study of technical characteristics, performance criteria, and other factors of radiolocation and radionavigation systems in the bands 9 000-9 200 MHz and 9 300-9 500 MHz and of the interference criteria for those systems. In addition, Resolution 747 (WRC-03) has established Agenda item 1.3 for WRC-07 to consider upgrading the allocations to the radiolocation service in the 9 000-9 200 and 9 300-9 500 MHz bands to co-primary and to consider extending the primary allocation to the Earth exploration-satellite (EES) (active) service and space research (SR) (active) service in the band 9 500-9 800 MHz band contiguously by 200 MHz. Characteristics of representative terrestrial radars in the 8 500 MHz-10.5 GHz band are contained in Recommendation ITU-R M.1796. This Report is a further contribution to the studies required by Question ITU-R 234/8 and Resolution 747 (WRC-03).
