The Technique of Measurement of the Pattern of Receive Phased Antenna Array for Automotive Radar

One of the main components of a radar system is the antenna. Measurement of the directivity pattern of the antenna system is of great practical importance for determining the level of angular resolution of radar. The classical method of determining the directivity pattern is very time consuming, especially when working with phased antenna arrays. An alternative method for measuring the directivity pattern is discussed in this article. The results of mathematical modeling of this approach and their comparison with experimental data are presented.
