Abstract:
Phased array radar antenna system, comprising at least two phased array antenna faces, both provided with an array of radiating elements, an array of T/R modules connected to the array of radiating elements, a summing network for the summation of output signals of the array of T/R modules and a control unit for the generation of control signals for the individual antenna faces, characterized in that each antenna face is provided with at least one canceller for at least substantially cancelling crosstalk signals produced by the at least one remaining antenna face, that a first input of the canceller is connected to the summing network that a second input of the canceller is connected to the controlled unit to enable the reception of control signals and that an output signal of the canceller is connected to the summator together with an output signal of the summing network.
