Abstract

The effective area of a receiving antenna in the form of the open end of a standard waveguide was measured in a numerical and real experiment using two different reference antennas. The receiving antenna is designed to register powerful microwave pulses. The influence of the phase center position of the transmitting antenna was taken into account during measurements of the receiving antenna effective area in the frequency band of 8–12 GHz. The possibility of reducing the effective area of the antenna at its constant value in the frequency band by optimizing the size of the diaphragms installed in the input window of the waveguide is investigated.
