1. A method for providing a redundant or distinct transmission feature to a communication system, comprising:

  • detecting at the communication system if there is a communication systems fault;

    if the communication systems fault is not detected, generating a plurality of modified transmit signals by combining a transmit signal with a plurality of complex weights and transmitting the plurality of modified transmit signals from a plurality of antenna elements of the communication system to an object of interest; and

    if the communication systems fault is detected, generating a plurality of redundant or distinct transmit signals by combining the transmit signal with a plurality of first orthogonal or approximately orthogonal numerical sequences and synchronously transmitting the plurality of redundant or distinct transmit signals from the plurality of antenna elements of the communication system.
