1. A digital phased array receiver for receiving electromagnetic energy, comprising:

  • a plurality of antenna elements capable of receiving electromagnetic energy;

    a receive module coupled to each of the plurality of antenna elements, the receive module including an analog to digital converter controlled by a sampling clock signal generated by clock circuitry coupled to a delay circuit; and

    synchronization circuitry coupled to the analog to digital converter to receive and then output data from the analog to digital converter at an output clock rate;

    wherein each delay circuit delays a base clock signal from the clock circuitry by a desired amount so that a receive direction of the plurality of antenna elements can be electronically controlled; and

    wherein the output clock rate for the synchronization circuitry matches the clock signal controlling the analog to digital converter.
