Abstract: SUMMARYIn this paper, a method is proposed for multi-beam forming of wideband signals by means of delay processors and two-dimensional fan filters. Only one axially symmetric two-dimensional fan filter is used. Multi-beam forming is carried out by multiplexing the delay processors for two-dimensional signals for each beam direction. The delay processing here corresponds to a rotation of the two-dimensional spectra in the two-dimensional frequency domain and provides a delay proportional to the sensor location…
