1. A combined radar and communications link, comprising:

  • a radar having a frequency source and an antenna for forming a radar beam;

    a unit at said radar for monitoring radar returns and for developing a signal reflecting a radar parameter;

    means for interrupting the normal radar beam when the particular parameter has been detected;

    a modulator coupled to said frequency source and said signal reflecting a radar parameter for modulating the signal transmitted by said radar antenna after normal beam interruption in accordance with said parameter, whereby modulated radiation from said radar antenna establishes said communications link; and

    wherein said radar is a CW radar and wherein said modulation is selected from the group consisting of amplitude modulation, frequency modulation, phase modulation and pulse code modulation.
