Uniformly spaced mm-band arrays in the development of techniques for measurement of elevation angles of low-altitude targets

The use of an antenna array permits one to register signals, received by each elementary antenna, and further processing of obtained data by computer simulations, allows considerable simplification of a realisation of special techniques for measuring elevation angles of low-altitude targets. To basic advantages of such an approach it is possible to refer: possibility of a realisation of practically any technique for measurement of elevation angle, including techniques requiring mechanical turn of antenna device during tracking of the target; possibility of a comparison of various techniques for measurement of elevation angles on the same realisations of electromagnetic field structure; and relative simplicity of realisation calibration of antenna system
