DEVICE FOR MEASURING low elevation angles GOALS Radar

摘要

Device for measuring small angles purposes place relates to the field of radar and may be used in radar stations (radar) located on the ground with a varying slope of the underlying surface, for measuring small elevation angles flying objects. The technical result is to increase the accuracy of measurement of small angles of radar targets in place when changing the inclination of the underlying surface. Said technical result is achieved due to the fact that in the known device, consisting of an antenna array, divided into two symmetrical sublattice with shifted phase centers and comprising N dipoles, N phase shifters, two adders, data preparation device solver and control the phase shifters, administered earth beam suppression circuit consisting of the N multipliers, and devices generating weighting coefficients for suppression earth beam tilt meter to alter the underlying surface Nia angular position of the antenna pattern, and a third adder for correcting the angle measurement results purposes place.
