1. A method, comprising:

  • taking a number of discrete samples of a received signal in an adaptive antenna array processing system;

    estimating a noise environment of the received signal from the discrete samples;

    applying a regularization constant to a covariance matrix of the received signal to regularize the estimated noise environment;

    adding a variable synthetic signal based on the regularized estimated noise environment to the received signal to reduce a noise contribution for noise at power levels below the regularization constant; and

    developing a spatial processing strategy based on the regularized noise environment.
