1. A phased array antenna comprising a first antenna element and a plurality of second antenna elements configured to receive signals, each of said antenna elements comprising a controllable oscillator configured to provide an output signal for use as part of a demodulation or down-conversion operation for converting a received signal to a frequency converted output signal of the antenna element, and wherein the phase of the output signal of the controllable oscillator of said first antenna element is adjustable responsive to a phase control signal representative of a comparison between the frequency converted output signal of the first antenna element and a composite of the frequency converted output signals of the first antenna element and the plurality of second antenna elements, such that said composite of the output signals has an improved signal-to-noise ratio.
