The properties of an adaptive array antenna, including transient response rate and control loop noise, depend on the intensity of the external noise field. The dependence can be reduced by a general envelope normalization. This can be done without degrading the performance of the adaptive array. Special cases of the normalization are envelope limiting, considered in [4], and one-bit digitization of the real and imaginary parts of the signal from which the envelopes are formed, considered in [5]. Another important special case is one-bit digitization of the imaginary part of the signal from which the envelopes are formed while the real part is set to zero.
