Organization: ITU-R
Publication Date: 1 January 2018
Status: active
Page Count: 26
scope:

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